TypeScript is a typed superset of JavaScript that compiles to plain JavaScript. It adds static typing and structuring mechanisms like classes, interfaces, and modules to JavaScript to help catch errors and provide better documentation for large scale JavaScript application development. Some key features of TypeScript include optional static types for functions and variables, classes with inheritance and static methods, interfaces, modules, generics, and type inference.
XAML is a declarative markup language used to define user interfaces for .NET applications. It separates the UI definition from application logic. XAML uses XML syntax to describe objects and controls that comprise a UI and defines their properties, events, and animations. Some key features of XAML include vector graphics, animations, styles, templates, and controls. XAML allows the UI and logic of an application to be developed independently using different tools.
Getting started with the reactjs, basics of reactjs, introduction of reactjs, core concepts of reactjs and comparison with the other libraries/frameworks
The document discusses various unit testing frameworks for .NET such as MSTest v2, NUnit, and xUnit.net. It provides information on the key features of each framework, how to install and set them up, how to write tests, and comparisons between the frameworks. The document recommends NUnit as it has the richest set of assertions, supports data-driven testing well, and has full documentation available, which would be important for a new development team to learn to use the framework effectively.

This document provides an overview and introduction to React JS. It discusses that React JS is a JavaScript library developed by Facebook for building user interfaces and reusable UI components. It encourages creation of reusable components that present data that changes over time. The document also covers React JS features, architecture, components, best practices, pros and cons, and provides useful links for examples and environment setup.

Best Practices for Running Oracle Databases on Amazon RDS (DAT317) - AWS re:I...Amazon Web Services
Amazon Relational Database Service (Amazon RDS) continues to be a popular choice for Oracle DBAs moving new and legacy workloads to the cloud. In this session, we discuss how Amazon RDS for Oracle helps DBAs focus their time where it matters most. We cover recent RDS Oracle features, and we go deep on key functionality that enables license optimization, performance, and high availability for Oracle databases. We also hear directly from an AWS customer about their journey to Amazon RDS and the best practices that helped make their move successful.
In this presentation, Prashant Sharma of Valuebound has talked about ReactJS - a JavaScript library for building user interfaces. Check out the agendas to know what is there for you.

TypeScript is a super set of JavaScript. This slide covers the key features of TypeScript including basics of typescript, basic types, Interfaces, Functions, Classes, Generics, Modules.
This document discusses unit and integration testing. It begins by explaining the benefits of testing, such as reducing bugs and allowing safe refactoring. It then describes different types of tests like unit, integration, and database tests. The document focuses on unit testing, explaining how to write and organize unit tests using PHPUnit. It provides examples of test assertions and annotations. It also covers mocking and stubbing dependencies. Finally, it discusses challenges like testing code that relies on external components and provides strategies for database testing.
This document contains an agenda and slides for a React workshop presented by Bojan Golubovic. The workshop covers the history and basics of React, including components, JSX, the virtual DOM, and React data flow. It also discusses related tools like Redux and React Router. The goal is to provide basic knowledge of React and how to build real-world applications with it.
Cypress is an e2e testing tool that allows for testing web applications directly in the browser. It provides native access to the browser without using Selenium, making tasks like taking screenshots and recording videos possible. Some limitations are that it only supports single-page applications and one browser tab at a time. Cypress prioritizes developer experience through features like fast testing, intuitive debugging, and integration with continuous integration systems and dashboards. Many large companies have adopted Cypress for their e2e testing needs.
This document discusses TypeScript, a superset of JavaScript that adds optional static typing and class-based object-oriented programming. It allows developers to gradually introduce typing into JavaScript code for improved productivity and catch errors early. The document covers TypeScript features like interfaces, classes, modules, type definitions, and comparisons to alternatives like CoffeeScript and Dart. It concludes that TypeScript allows gradual adoption of typing while following the future ECMAScript standard.
Slide 1
TypeScript
* This presentation is to show TypeScript's major feature and the benefit that it brings to your JavaScript projects.
* Our main objective is just to spark interest especially to those not familiar with the tool.
Slide 2
- What is TypeScript
* go to next slide
Slide 3
- Is a superset of JavaScript
* it simply means an extension to JavaScript
- Use JavaScript code on TypeScript
* JS code naturally works on TypeScript
* Which also means your beloved JavaScript libraries such as JQuery, or your fancy interacive plugins would work as well.
- TypeScript compiles to plain old JavaScript
* TS code compiles to simple and clean JS.
Slide 4
- Screenshot of TS compiled to JS
* In this example, compiling a TS class code would result to a JS version, and a regular JavaScript function when compiled is basically untouched.
Slide 5
- TypeScript's Main Feature
* So what does TS provide us with? What does it actually do?
Slide 6
- Static Type Checking
* TypeScript allows us to enable type checking by defining data types to your for ex. variables, function parameters and return types.
Slide 7
- Screenshot of basic Static Type Checking
* In this example…
* What I've done here was to assign supposedly wrong values for what the variables or parameters were meant to hold
* As JavaScript is a dynamic and untyped language these expressions would either fail or be okay when you run it on your browser.
* In TypeScript by enabling static type checking these potential errors are caught earlier (see the red marks on the expressions) and wouldn't even allow you to compile unless these are resolved.
* In addition you can also type arrays and object literals
Slide 8
- Effects of Static Type Checking
* As TS code is statically type-checked a side effect of such...
- Allows IDEs to perform live error checks
- Exposes auto-completion and code hinting
Slide 9
- Screenshot of code hinting
* Say I was coding JQuery on regular JavaScript code there would be no natural way to help me identify its class properties, methods and parameters... except through reading the API documentation or a separate plugin.
* As a result of static type checking this allows IDE's to access these class members as code hints
* So if this was a 3rd party library how much more if you are just referencing your own JavaScript/TypeScript files within your project.
Slide 10
- A few of the other cool features
* That was only the basic feature of TypeScript
* A few of the other cool features are...

This document provides an overview of unit testing in Angular, including setting up Angular CLI for testing, the tools used for testing like Karma and Jasmine, how to write test specs with expectations and matchers, how to set up and tear down tests, and how to test different parts of an Angular application like components, templates, dependencies, and HTTP services. The agenda also includes debugging tests and generating code coverage reports.
