Generally speaking, a function is a "subprogram" that can be called by code external (or internal in the case of recursion) to the function. Like the program itself, a function is composed of a sequence of statements called the function body. Values can be passed to a function, and the function will return a value.
In JavaScript, functions are first-class objects, because they can have properties and methods just like any other object. What distinguishes them from other objects is that functions can be called. In brief, they are Function objects.
JavaScript - Chapter 9 - TypeConversion and Regular Expressions WebStackAcademy
Type Conversion:
JavaScript is loosely typed language and most of the time operators automatically convert a value to the right type but there are also cases when we need to explicitly do type conversions.
While JavaScript provides numerous ways to convert data from one type to another but there are two most common data conversions :
Converting Values to String
Converting Values to Numbers
Regular Expressions:
A regular expression is an object that describes a pattern of characters.
The JavaScript RegExp class represents regular expressions, and both String and RegExp define methods that use regular expressions to perform powerful pattern-matching and search-and-replace functions on text.
In JavaScript, almost "everything" is an object.
-Booleans can be objects (if defined with the new keyword)
-Numbers can be objects (if defined with the new keyword)
-Strings can be objects (if defined with the new keyword)
-Dates are always objects
-Maths are always objects
-Regular expressions are always objects
-Arrays are always objects
-Functions are always objects
-Objects are always objects
JavaScript - Chapter 4 - Types and StatementsWebStackAcademy
A computer program is a list of "instructions" to be "executed" by a computer.
In a programming language, these programming instructions are called statements.
A JavaScript program is a list of programming statements.
JavaScript statements are composed of:
Values, Operators, Expressions, Keywords, and Comments.
This statement tells the browser to write "Hello Dolly." inside an HTML element with id="demo":
JavaScript Data Types
JavaScript variables can hold many data types: numbers, strings, objects and more.
In programming, data types is an important concept.
To be able to operate on variables, it is important to know something about the type.

( ** Full Stack Web Development Training: https://www.edureka.co/masters-program/full-stack-developer-training ** )
This Edureka tutorial on JavaScript explains all the fundamentals of JavaScript with examples. It also explains various features and applications of JavaScript. Following are the topics included in this tutorial:
1. What Is JavaScript?
2. Why Use JavaScript
3. JavaScript Fundamentals
- Data Types
- Variables
- Constants
- Loops
- Conditional Statements
- Functions
A JavaScript function is a block of code designed to perform a particular task.
Why Functions?
You can reuse code: Define the code once, and use it many times. You can use the same code many times with different arguments, to produce different results.
JavaScript Events:
HTML events are "things" that happen to HTML elements. When JavaScript is used in HTML pages, JavaScript can "react" on these events.
What can JavaScript Do?
Event handlers can be used to handle, and verify, user input, user actions, and browser actions:
Things that should be done every time a page loads
Things that should be done when the page is closed
Action that should be performed when a user clicks a button
Content that should be verified when a user inputs data
JavaScript - An Introduction is a beginner's guide to JavaScript. It starts with very basic level and goes to intermediate level. You'll be introduced with every language constructs, Event handling, Form handling and AJAX which is supported by JavaScript with XMLHttpRequest object. This XHR object is discussed in enough detail so that you can understand how the underlying AJAX functionality works in jQuery. At the end it discusses advance concepts and library build on/around JavaScript.
Angular - Chapter 4 - Data and Event HandlingWebStackAcademy
In Angular , events such as button click or any other sort of events can also be handled very easily. The events get triggered from the html page and are sent across to Angular JS class for further processing.
Data binding is a core concept in Angular and allows to define communication between a component and the DOM, making it very easy to define interactive applications without worrying about pushing and pulling data. There are four forms of data binding and they differ in the way the data is flowing.
A presentation of what are JavaScript Promises, what problems they solve and how to use them. Dissects some Bluebird features, the most complete Promise library available for NodeJS and browser.

Angular - Chapter 9 - Authentication and AuthorizationWebStackAcademy
Authentication is the process of validating a user on the credentials (username and password)
and provide access to the web application(ex: Email)
Authorization helps you to control access rights by granting or denying specific permissions
to an authenticated user (Ex: User / Manager / Admin).
Http Service will help us fetch external data, post to it, etc. We need to import the http module to make use of the http service. Let us consider an example to understand how to make use of the http service.
AngularFire is the officially supported AngularJS binding for Firebase. ... The focus of this library is to abstract much of the boilerplate involved in creating Angular bindings from Firebase to Angular, and to make it easy to create services that sync to your database.
A directive is a custom HTML element that is used to extend the power of HTML. Angular 2 has the following directives that get called as part of the BrowserModule module.
ngif
ngFor
If you view the app.module.ts file, you will see the following code and the BrowserModule module defined. By defining this module, you will have access to the 2 directives.
Components are the most basic UI building block of an Angular app. An Angular app contains a tree of Angular components.
Angular components are a subset of directives, always associated with a template. Unlike other directives, only one component can be instantiated per an element in a template.
A component must belong to an NgModule in order for it to be available to another component or application. To make it a member of an NgModule, list it in the declarations field of the NgModule metadata.
TypeScript lets you write JavaScript the way you really want to. TypeScript is a typed superset of JavaScript that compiles to plain JavaScript. TypeScript is pure object oriented with classes, interfaces and statically typed like C# or Java. The popular JavaScript framework Angular 2.0 is written in TypeScript. Mastering TypeScript can help programmers to write object-oriented programs and have them compiled to JavaScript, both on server side and client side.
AngularJS is a structural framework for dynamic web apps. It lets you use HTML as your template language and lets you extend HTML's syntax to express your application's components clearly and succinctly. AngularJS's data binding and dependency injection eliminate much of the code you would otherwise have to write. And it all happens within the browser, making it an ideal partner with any server technology.
JavaScript String:
The String object lets you work with a series of characters; it wraps Javascript's string primitive data type with a number of helper methods.
As JavaScript automatically converts between string primitives and String objects, you can call any of the helper methods of the String object on a string primitive.
JavaScript Arrays:
The Array object lets you store multiple values in a single variable. It stores a fixed-size sequential collection of elements of the same type. An array is used to store a collection of data, but it is often more useful to think of an array as a collection of variables of the same type.
Debugging in JavaScript
It is common to have errors while writing codes and the errors can be due to syntax or logical. These errors create a lot of ambiguity in the logic and understanding of both users and programmers. There can also be errors in the code which can remain invisible to the programmer’s eye and can create havoc. To identify these errors we need Debuggers that can go through the entire code or program, identify the errors and also fix them.
-Debugger
The debugger keyword is used in the code to force stop the execution of the code at a breaking point and calls the debugging function. The debugger function is executed if any debugging is needed at all else no action is performed.
Form validation normally used to occur at the server, after the client had entered all the necessary data and then pressed the Submit button. If the data entered by a client was incorrect or was simply missing, the server would have to send all the data back to the client and request that the form be resubmitted with correct information. This was really a lengthy process which used to put a lot of burden on the server.
JavaScript provides a way to validate form's data on the client's computer before sending it to the web server. Form validation generally performs two functions.
Basic Validation − First of all, the form must be checked to make sure all the mandatory fields are filled in. It would require just a loop through each field in the form and check for data.
Data Format Validation − Secondly, the data that is entered must be checked for correct form and value. Your code must include appropriate logic to test correctness of data.
The Browser Object Model (BOM) in JavaScript includes the properties and methods for JavaScript to interact with the web browser.
BOM provides you with window object, for example, to show the width and height of the window. It also includes the window.screen object to show the width and height of the screen.
What is the DOM?
The DOM is a W3C (World Wide Web Consortium) standard.
The DOM defines a standard for accessing documents:
"The W3C Document Object Model (DOM) is a platform and language-neutral interface that allows programs and scripts to dynamically access and update the content, structure, and style of a document."
The W3C DOM standard is separated into 3 different parts:
Core DOM - standard model for all document types
XML DOM - standard model for XML documents
HTML DOM - standard model for HTML documents
The HTML DOM (Document Object Model)
When a web page is loaded, the browser creates a Document Object Model of the page.
The HTML DOM model is constructed as a tree of Objects.
With the HTML DOM, JavaScript can access and change all the elements of an HTML document.
JavaScript Arithmetic Operators
Arithmetic operators are used to perform arithmetic between variables and/or values.
JavaScript Assignment Operators
Assignment operators are used to assign values to JavaScript variables.
JavaScript String Operators
The + operator, and the += operator can also be used to concatenate (add) strings.
Comparison Operators
Comparison operators are used in logical statements to determine equality or difference between variables or values.
Conditional (Ternary) Operator
The conditional operator assigns a value to a variable based on a condition.
Logical Operators
Logical operators are used to determine the logic between variables or values.
JavaScript Bitwise Operators
Bit operators work on 32 bits numbers. Any numeric operand in the operation is converted into a 32 bit number. The result is converted back to a JavaScript number.
The delete Operator
The delete operator deletes a property from an object:
Threats to mobile devices are more prevalent and increasing in scope and complexity. Users of mobile devices desire to take full advantage of the features

Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Function Invocation Patterns
●
The code in a function is not executed when the function is defined
●
Function is executed when it is invoked
●
Functions can be invoked in 4 different ways
– Invoking a function as a “function”
– Invoking a function as a “method”
– Invoking a function with a “Constructor function”
– Invoking a function with a “apply and call”
6. www.webstackacademy.com ‹#›
Invocation pattern
(invoking as method)
●
When a function is part of an object, it is called a method
●
Method invocation is the pattern of invoking a function
that is part of an object
●
JavaScript will set the this parameter to the object where
the method was invoked on
●
JavaScript binds this at execution (also known as late
binding)
7. www.webstackacademy.com ‹#›
Invocation pattern
(invoking as method)
<script>
var obj = { firstName: "Smith", lastName: "Doe",
fullName: function() {
return this.firstName + " " + this.lastName;
}
};
// In the example above, this would be set to obj
document.write("Full name is " + obj.fullName());
</script>
8. www.webstackacademy.com ‹#›
Invocation pattern
(Constructor invocation)
●
The constructor invocation pattern involves putting the new
operator just before the function is invoked
●
If the function returns a primitive type (number, string, boolean, null
or undefined)
– The return will be ignored and instead this will be returned
(which is set to the new object)
●
If the function returns an instance of Object
– The object will be returned instead of returning this
9. www.webstackacademy.com ‹#›
Invocation pattern
(Constructor invocation - 1)
<script>
var Fullname = function(firstname, lastname) {
// create a property fullname
return this.fullname = firstname + ‘ ’ + lastname;
};
var obj = new Fullname(“Tenali”, “Raman”);
document.write("Full name is " + obj.fullname);

Invocation pattern
(Constructor invocation - 2)
<script>
var Fullname = function(firstname, lastname) {
// return object
return { fullname : firstname + ‘ ’ + lastname }
};
var obj = new Fullname(“Tenali”, “Raman”);
document.write("Full name is " + obj.fullname);
</script>

Invocation pattern
(with apply() and call() methods)
●
JavaScript functions are objects and have properties and
methods
●
The call() and apply() are predefined method, invoke the
function indirectly
●
The call() method uses its own argument list as arguments to
the function
●
The apply() method expects an array of values to be used as
arguments
14. www.webstackacademy.com ‹#›
Function Expression
Syntax:
var func = function (param-1, param-2, . . . , param-n) {
statement(s);
}
●
Variable can be used to invoke the function
●
Above function is an anonymous function (a function
without a name)
15. www.webstackacademy.com ‹#›
Function Hoisting
●
JavaScript moves variable and function declarations to top of
the current scope; this is called hoisting
●
Due to hoisting JavaScript functions can be called before they
are declared
var s = sum (x, y);
function sum (x, y) {
return x + y;
}
function sum (x, y) {
return x + y;
}
var s = sum (x, y);
17. www.webstackacademy.com ‹#›
Self Invoking Function
●
Function expressions can be used to self-invoke function
(start automatically without being called)
●
This is done by using parenthesis () -- also known as
function invocation operator
Syntax:
( function_expression ) ( );
18. www.webstackacademy.com ‹#›
Self Invoking Function
Example:
( function () {
document.write(“I am self invoking function”);
} ) ( );
●
Such expressions also known as IIFE (Immediately
Invokable Function Expression

JavaScript Scopes
(what?)
●
Scope determines the accessibility (or visibility) of variables,
objects, and functions from different parts of the code at
runtime
●
JavaScript has two types of scope
– Local scope
– Global scope
●
Please note that, in JavaScript, objects and functions are
also variables
20. www.webstackacademy.com ‹#›
JavaScript Scopes
(why?)
●
Scope provides security to data that, in principle, shall be
accessed only by intended part of the code
●
If data is exposed to all parts of program then it can be
modified anytime without your notice which will lead to
unexpected behaviour and results
●
Scope also allow use to use same names in different
functions
21. www.webstackacademy.com ‹#›
JavaScript Scopes
(Local Scope)
●
Variables defined within a function are local to the function
●
Such variables have local scope and can’t be accessed
outside the function
●
Since local variables are only recognized inside their
functions, variables with the same name can be used in
different functions
●
Local variables are created when a function is invoked
(started), and deleted when the function exits (ended)
22. www.webstackacademy.com ‹#›
JavaScript Scopes
(Local Scope)
<script>
function square(num) {
var result = num * num; // variable with local scope
}
Square(3); // invoke the function
document.write(“Square of number = ” + result); // Exception
</script>
23. www.webstackacademy.com ‹#›
JavaScript Scopes
(Global Scope)
●
Variables defined outside a function have global scope
●
Such variables are visible to all the functions within a
document, hence, can be shared across functions
24. www.webstackacademy.com ‹#›
JavaScript Scopes
(Global Scope)
<script>
var result; // variable with global scope
function square(num) {
result = num * num;
}
square(3); // invoke the function
document.write(“Square of number = ” + result);
</script>
25. www.webstackacademy.com ‹#›
JavaScript Scopes
(Function and block scopes)
●
Further, in JavaScript, there are two kinds of local scope
– Function scope
– Block scope
●
A block of code is created with curly braces { }
●
Conditional statements (if, switch) and loops (for, while,
do-while) do not create new scope
26. www.webstackacademy.com ‹#›
JavaScript Scopes
(How variables are created?)
●
JavaScript processes all variable declarations before
executing any code, whether the declaration is inside a
conditional block or other construct
●
JavaScript first looks for all variable declarations in given
scope and creates the variables with an initial value of
undefined
●
If a variable is declared with a value, then it still initially has
the value undefined and takes on the declared value only
when the line that contains the declaration is executed
27. www.webstackacademy.com ‹#›
JavaScript Scopes
(How variables are created?)
●
Once JavaScript has found all the variables, it executes
the code
●
If a variable is implicitly declared inside a function -
– Variable has not been declared with keyword “var”
– And, appears on the left side of an assignment
expression
is created as a global variable
29. www.webstackacademy.com ‹#›
JavaScript Scopes
(Global Scope)
●
Global variables are not automatically created in "Strict Mode"
<script>
function square(num) {
“use strict”;
result = num * num;
}
document.write(“Square of number = ” + result); // Exception
</script>
30. www.webstackacademy.com ‹#›
JavaScript Scopes
(Global Scope)
●
Global variables belong to window object
<script>
function square(num) {
result = num * num;
}
document.write(“Square of number = ” + window.result);
</script>
32. www.webstackacademy.com ‹#›
JavaScript Scopes
(Function scope variable)
<script>
function func() {
var x = 10; // function scope variable
{
var x = 20; // function scope variable
document.write("<br>x = " + x); // shall print 20
}
document.write("<br>x = " + x); // shall print 20
}
</script>
33. www.webstackacademy.com ‹#›
JavaScript Scopes
(Block scope variable)
●
ECMA script 6 has introduced keywords “let” and “const”
●
Variables declared using these keywords will have block
level scope
●
For these variables, the braces {. . .} define a new scope
34. www.webstackacademy.com ‹#›
JavaScript Scopes
(Block scope variable - let)
<script>
function func() {
let x = 10;
{
let x = 20;
document.write("<br>x = " + x); // shall print 20
}
document.write("<br>x = " + x); // shall print 10
}
</script>

JavaScript Scopes
(Life time of variables)
Variable Keyword Scope Life time
Local Var Function ●
Created when function is invoked
●
Deleted when function exits
Let, const Function or
block
●
Created when function is invoked
●
Deleted when function exits
Global var, let,
const
Browser
Window
●
Created when web page is loaded in the
browser window (tab)
●
Deleted when browser window (tab) is closed
var, let,
const
Block ●
Created when block is entered
●
Deleted when block is exited
●
Life time of a variable is the time duration between it’s creation
and deletion
37. www.webstackacademy.com ‹#›
JavaScript Scopes
(important notes)
●
Do not create global variables unless needed
●
Your global variables or functions can overwrite window
variables or functions
●
Opposite is also possible; any function (including window
object) can overwrite your global variables and functions
38. www.webstackacademy.com ‹#›
Function Closures
●
In JavaScript, an inner (nested) function stores
references to the local variables that are present in the
same scope as the function itself, even after the function
returns
●
The inner function has access to the outer function's
variables; this behavior is called lexical scoping
●
However, the outer function does not have access to the
inner function's variables
39. www.webstackacademy.com ‹#›
Function Closures
●
A closure is an inner function that has access to the outer
function’s variables – scope chain
●
The closure has three scope chains:
– It has access to its own block scope (variables defined
between its curly brackets)
– It has access to the outer function’s variables
– It has access to the global variables
40. www.webstackacademy.com ‹#›
Function Closures
(Example)
<script>
function disp() { // Parent function
var name = "Webstack Academy"; // name is a local variable
displayName() { // displayName() is the inner function, a closure
alert (name); // The inner function uses variable of parent function
}
displayName(); // child function call
}
disp(); // parent function call
</script>

Recursion
●
Recursion is the process in which a function is called by
itself
●
Recursion is a technique for iterating over an operation
by having a function call itself repeatedly until it arrives at
a result
