jQuery is drawing newcomers to JavaSCript in droves. As a community, we have an obligation -- and it is in our interest -- to help these newcomers understand where jQuery ends and JavaScript begins.
Type safe embedded domain-specific languagesArthur Xavier
Language is everything; it governs our lives: from our thought processes, our communication abilities and our understanding of the world, all the way up to law, politics, logic and programming. All of these domains of human experience are governed by different languages that talk to each other, and so should be your code. Haskell provides all the means necessary—and many more—to easily and safely use embedded small languages that are tailored to specific needs and business domains.
In this series of lectures and workshops, we will explore the whats, whys and hows of embedded domain-specific languages in Haskell, and how language oriented programing can bring type-safety, composability and simplicity to the development of complex applications.
How else can you write the code in PHP?Maksym Hopei
Usually we are limited with our environment and habits. When we make changes to a product or when we work with a team we follow the coding standards and the existing approaches to make our life and life of our teammates easier.
But often we do the same when we start a new product on our own ruled by our habits and by the limitations of our horizon.
This talk is intended to introduce some uncustomary ways to write code.

SenchaCon 2016: Add Magic to Your Ext JS Apps with D3 Visualizations - Vitaly...Sencha
Ext JS provides easy-to-use charting components that satisfy common needs, but sometimes you want to deliver an exceptional, unique user experience. This presentation will discuss how Ext JS leverages the popular and extremely powerful D3 library to create sophisticated, data-driven visualizations. This functionality helps your users understand the story behind their data, so they can make informed decisions.
Talk I gave at Maceió DEV Meetup #6. Not only about Command Bus/Command Interface or whatever you name it, but a compilation of cool articles I found only that may help with understanding this architecture.

JavaScript Fundamentals with Angular and LodashBret Little
The purpose of this presentation is also largely to explain some of the fun parts of JavaScript (dynamic function invocation with reflection, dynamic arguments, etc). I don't necessarily encourage putting complex logic throughout your templates with lodash, though there may be times it is appropriate.
Lets talk about lodash and how it can easily be married to Angular. Using a six line filter, I will expose the power of lodash directly within angular templates. This will be an introduction to lodash, angular templates, and we'll talk about scope and reflection within JavaScript.
Functional programming is becoming more and more popular. It's quite obvious that there are many benefits on using FP elements on server side. How does it look like in JavaScript world? I will focus on functional concepts that can improve our every day work. I won't talk about monads, functors and other mathematical concepts. We'll see how functional style can improve our codebase, make it more readable or simplify complex problems. Samples will be presented in JavaScript, but concepts are general for every programming language.

A closure in JavaScript is a function that has access to variables in its parent scope, even after the parent function has returned. Closures are created when a function is defined inside another function, and the inner function retains access to the variables in the outer function’s scope.
Here is an example of a closure in JavaScript:In this example, the innerFunction is a closure because it has access to the variable x and innerVar from the outerFunction even after outerFunction has returned.
A closure has three scope chains:
It has access to its own scope (variables defined between its curly braces {}).
It has access to the outer function’s variables.
It has access to the global variables.
Closures are commonly used in JavaScript for a variety of tasks, such as:
Implementing private methods and variables.
Creating callback functions that retain access to variables from their parent scope.
Creating and returning an object that has access to variables from its parent scope.
JavaScript closures are an important concept and it is important to understand how closures work in JavaScript. It is also important to be aware of the scope chain, and how closures interact with the scope chain.JavaScript Object Notation (JSON) is a lightweight data-interchange format that is easy for humans to read and write and easy for machines to parse and generate. It is based on a subset of the JavaScript Programming Language, Standard ECMA-262 3rd Edition – December 1999. JSON is a text format that is completely language independent but uses conventions that are familiar to programmers of the C-family of languages, including C, C++, C#, Java, JavaScript, Perl, Python, and many others. These properties make JSON an ideal data-interchange language.
Sample JavaScript Code Laurence Svekis
JavaScript Closure
A closure in JavaScript is a function that has access to the variables in its parent scope, even after the parent function has completed execution. This allows for data to be “closed over” or remembered by the inner function, even after the outer function has returned.
Here, the makeCounter function returns an inner function that has access to the count variable declared in its parent scope, and can “remember” the current count value even after the makeCounter function has completed execution. Each time the inner function is called, it returns the current value of count and increments it by 1.
JavaScript Closure Advanced
In this example, the makeAdder function takes in a single argument x and returns an inner function that takes in a second argument y. The inner function has access to the x variable declared in the parent scope and uses it to add x and y together and return the result.
We can see here that the outer function makeAdder has been executed twice and it returns two different inner functions which are assigned to different variables add5 and add10 and these inner functions are able to remember their respective parent scope values of x.
Profile Picture
Use a professional profile picture: A professional headshot is essential for making a good first impression on potential connections and employers.
Headline
Write a compelling headline: Your headline is the first thing people see when they come across your profile, so make sure it accurately reflects your professional brand and grabs their attention.
Your Summary
Optimize your summary: Your summary is your chance to tell your professional story and highlight your unique skills and experiences.
Job Experience
List your current and past job experiences: Make sure to include your current job title, company, and a brief description of your role, as well as your past job experiences.
Highlight Skills
Highlight your skills: Use the skills section to highlight your strengths and areas of expertise. This will make it easier for potential employers to find you when searching for candidates with specific skills.
Get endorsements
Get endorsements and recommendations: Endorsements from your connections and recommendations from past employers can help boost your credibility and make you stand out.
Groups
Join relevant groups: Joining groups in your industry can help you stay up-to-date on industry news and connect with other professionals in your field.
Content
Share valuable content: Share relevant articles, blog posts, and other content to demonstrate your industry knowledge and establish yourself as a thought leader.
Be Active
Be active: Regularly update your profile and engage with your connections by liking, commenting, and sharing their content.
Contact Info
Make it easy to contact you: Include your contact information, such as your email address and phone number, so that potential employers and connections can easily get in touch with you.
Conclusion
Overall, your LinkedIn profile is your professional online identity, so invest time and effort to make it as complete and professional as possible. It’s a living document that should be updated regularly with your latest experiences, skills, and achievements.
Top questions with answers and code examples for JavaScript
JavaScript interview questions with answers:
What is closure in JavaScript and how does it work?
Answer: Closure is a feature in JavaScript where a function has access to its outer scope even after the outer function has returned. It is created when a function is defined inside another function, and the inner function retains access to the variables in the outer function’s scope. How do you declare a variable in JavaScript?
Answer: Variables in JavaScript can be declared using the “var”, “let” or “const” keywords. The “var” keyword is used to declare a variable with function scope, while “let” and “const” are used to declare variables with block scope.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

courses and many platforms.
3. What are objects -
in JavaScript
When it comes to writing code there are mays ways to
create a solution.
object is a collection of properties, and a property is an
association between a name ( key) and a value. A property's
value can be a function, in which case the property is known
as a method.
4. Object Literal
notation
Objects contain data and can use that data to return
results.
// Literal notation
var myObj1 = {
stuff: "yes"
, greet: "hello"
};
const person = {
first: "Laurence"
, last: "Svekis"
, id: 100
, details: function () {
return `${this.last}, ${this.first} id#${this.id}`
}
}
5. TRY IT Create an object that reflects a car.
Add Color, make, model, price, year then for bonus
points add a few methods like drive and park. Output
to console.
9. <body>
<script>
var myObj = {
"people": [ {
"firstName": "Mike"
, "lastName": "Smith"
, "age": 30
}, {
"firstName": "John"
, "lastName": "Jones"
, "age": 40
}]
};
myObj.people.forEach(function (item) {
console.log(item.firstName + " " + item.lastName);
let div = document.createElement('div');
div.innerHTML = `<h3>${item.firstName}</h3>${item.lastName}`;
div.style.border = "1px solid #ddd";
div.style.display = "inline-block";
div.style.width = "100px";
document.body.appendChild(div);
})

10. Challenge #1 Shopping CART
1. Create an array that contains a typical selection
of items you might find going shopping.
2. Create JavaScript code to output it on the page
as divs.
3. Add an event listener that when clicked adds
the selected item to a global object and
updating the quantity if the item is already
there.
4. Create a method within the new object that
calculates the subtotal
*You can add styling as needed to make it look nice :)
12. Challenge #1 Shopping CART (part 2)
1. Add a cart on your page so that selected items
are visible.
2. Update it as new items are added
3. Add a total to the bottom
*Go shopping and enjoy.
13. const output = document.createElement('div');
document.body.appendChild(output);
items.forEach(function (ele) {

14. JavaScript Object
Oriented
Programming OOP
Objects are used to model and organize code. Grouping
similar items and tasks into what is known as a class.
It provide more flexibility and easier to extend on.
Class - it is the blueprint a template definition of an objects
properties and methods.
15. JavaScript Object
Constructor
notation
Uses class and new to construct the object. This makes it
easier to make many objects using the blueprint.
// Literal notation
var myObj1 = {
stuff: "yes"
, greet: "hello"
};
// Constructor notation
function Blueprint() {
this.stuff = "yes";
this.greet = "hello";
};
var myObj2 = new Blueprint();
var myObj3 = new Blueprint();
16. Constructor functions
Creating a new object using a function. The
constructor function is JavaScript's version of a
class.
Nothing is returned it defines properties and
methods
this keyword : name property will be equal to the
name value passed to the constructor call,
important tso they have their own values.
<script>
function Person(firstName, lastName) {
this.first = firstName;
this.last = lastName
this.greeting = function () {
console.log(`Hello ${this.first} ${this.last}`)
};
}
const tester = new Person('Laurence', 'Svekis');
console.log(tester.first);
tester.greeting();
</script>
TRY IT :
● Create several different objects using the constructor function.
● Invoke the greeting for each
17. TRY IT Its back.. But now use the function to construct the
object. Make a few cars…… Honda and Mustang and
more if you want. It’s easy :)
Also add a sell method that returns the minimum what
you want to sell it based on 90% of the price. Output
should match the sample.
18. const honda = new Car("Red", "Honda", "Accord", 45000, 2020);
const mustang = new Car("Black", "Ford", "Mustang", 50000, 1965);
function Car(color, brand, make, price, year) {
this.color = color;
this.brand = brand;
this.make = make;
this.price = price;
this.year = year;
this.tires = 4;
this.drive = function () {
console.log("I'm driving " + this.brand + " " + this.make + ", vrooom vrooom");
}
this.park = function () {
console.log("parking the " + this.brand);
}
this.sell = function () {
console.log("I want at least $" + this.price * .9 + " for the " + this.make + " I paid " + this.price);
}
}
Solution Car object
19. Challenge #2 Dice Game
1. Create an element on the page that can be
clicked
2. Create a constructor function to contain the
game functions calling it DiceGame
3. DiceGame Add option to roll the dice. Math
random 1-6
4. DiceGame Add option to check winner
5. In the click event add the roll for player and
computer using DiceGame
6. In the click event use DiceGame object to
determine winner and get result string.
7. Output the result to the clickable element
*You can add styling as needed to make it look nice :)
20. const game = new DiceGame();
const dice = document.createElement('div');
dice.textContent = "Roll Here";
document.body.appendChild(dice);
dice.addEventListener('click', function () {
let playerRoll = game.roll();
let compRoll = game.roll();
let winner = game.checker(playerRoll, compRoll);
console.log(winner);
dice.innerHTML = `Player ${playerRoll} vs Computer
${compRoll} <br> ${winner}`;
})
Dice Game - #2
function DiceGame() {
this.roll = function () {
this.result = Math.floor(Math.random() * 6) + 1;
return this.result;
}
this.checker = function (roll1, roll2) {
if (roll1 > roll2) {
return 'Player Wins';
}
else if (roll2 > roll1) {
return 'Computer Wins';
}
else {
return 'Tie';
}
}
}
21. Challenge #3 Shopping Cart
● Create DOM elements for input and adding
items to the store
● Add event listeners
● Create Objects for items
● Add shipping and tax to object
● Create Cart object
● Create adder method
● Create total cost method
● Create output of cart items
● Setup default item for testing
*Your application should be able to add items, click
new items and add them to a cart.
23. function Item(name, cost) {
this.name = name;
this.cost = cost;
this.withTax = function () {
return (this.cost * 1.15).toFixed(2);
}
this.shipping = function () {
return (this.cost * 1.05).toFixed(2);
}
}
function Cart() {
const myList = {};
this.totalCost = function () {
let total = 0;
for (let pro in myList) {
let subTotal = myList[pro].subtotal();
total += subTotal;
}
return total;
}
Challenge #3 Shopping Cart
this.output = function () {
let total = 0;
output1.innerHTML = "";
for (let pro in myList) {
let subTotal = myList[pro].subtotal();
total += subTotal;
output1.innerHTML += `${myList[pro].name}
$${myList[pro].price} x ${myList[pro].qty} = $${subTotal}<br>`
console.log(pro)
}
output1.innerHTML += `Final Total $${total}`;
}
this.adder = function (item, cost) {
let namer = item.toLowerCase();
if (!myList[namer]) {
myList[namer] = {
name: item
, price: cost
, qty: 1
, subtotal: function () {
return this.price * this.qty } } }
else {
myList[namer].qty++;
} } }
