Why did Angular 2 use TypeScript?

Conclusions. Angular 2 embraces the current latest and greatest technologies of the front-end world. In addition, by using TypeScript to write code, it boosts up the productivity of the developers. As we saw, the framework is completely re-written and helps you in doing many things in a simpler way.

What is TypeScript and how will it be useful in Angular?

TypeScript simply compiles/transpiles code down to ES5 or ES2015 depending on what you configure. TypeScript supports core ES2015 features as well as ES2016/ES2017 features like decorators, async/await and others. I like to think of it as ES2015++. See supported features at http://kangax.github.io/compat-table/es6.

What is TypeScript used for Angular?

TypeScript is a primary language for Angular application development. It is a superset of JavaScript with design-time support for type safety and tooling. Browsers can’t execute TypeScript directly. Typescript must be “transpiled” into JavaScript using the tsc compiler, which requires some configuration.

What is TypeScript vs Angular?

First of all, Angular is based on TypeScript while AngularJS is based on JavaScript. TypeScript is a superset of ES6 and it’s backward compatible with ES5. Angular has also benefits of ES6 like: lambda operators, iterators or reflection’s mechanism. AngularJS uses terms of scope and controller.

Why do we need TypeScript?

The goal of TypeScript is to help catch mistakes early through a type system and to make JavaScript development more efficient. Essentially TypeScript achieves its goals in three ways: Support for modern JavaScript features – The JavaScript language (not the runtime) is standardized through the ECMAScript standards.

What kind of data the observables help to manage in angular 2 +?

Observables help you manage asynchronous data, such as data coming from a backend service. Observables are used within Angular itself, including Angular’s event system and its HTTP client service. To use observables, Angular uses a third-party library called Reactive Extensions (RxJS).

Why is TypeScript useful?

TypeScript is a superset of JavaScript which primarily provides optional static typing, classes and interfaces. One of the big benefits is to enable IDEs to provide a richer environment for spotting common errors as you type the code.

What TypeScript is used for?

TypeScript may be used to develop JavaScript applications for both client-side and server-side execution (as with Node. js or Deno). There are multiple options available for transcompilation. Either the default TypeScript Checker can be used, or the Babel compiler can be invoked to convert TypeScript to JavaScript.

Do we need to learn TypeScript for angular?

You don’t need to learn it prior to Angular 2. You don’t even need to learn TypeScript at all. But that does not mean that you should not learn TypeScript. The beauty of TypeScript lies in the fact that is a superset of JavaScript and thus, all JavaScript is also valid TypeScript.

Do you have to use TypeScript with angular?

Angular says you do not have to use TypeScript. However, all of their documentation uses TypeScript, so I am not presented with much of a choice. For now, the contents of our file have not changed because we did not use any TypeScript specific syntax. To execute the code we wrote, run the command node helloWorld.

Should you learn TypeScript?

TypeScript is 100\% worth it. It’s how JavaScript should have been by default. The combination of static type checking with intelligent code completion provides a significant boost in developer productivity. Not only can you work faster, but you can also catch a ton of errors before they arise.
