Question

List some features of Typescript?

Answer 1

Object-Oriented language: TypeScript provides a complete feature of an object-oriented programming language such as classes, interfaces, inheritance, modules, etc. In TypeScript, we can write code for both client-side as well as server-side development.

TypeScript supports JavaScript libraries: TypeScript supports each JavaScript elements. It allows the developers to use existing JavaScript code with the TypeScript. Here, we can use all of the JavaScript frameworks, tools, and other libraries easily.

JavaScript is TypeScript: It means the code written in JavaScript with valid .js extension can be converted to TypeScript by changing the extension from .js to .ts and compiled with other TypeScript files.

TypeScript is portable: TypeScript is portable because it can be executed on any browsers, devices, or any operating systems. It can be run in any environment where JavaScript runs on. It is not specific to any virtual-machine for execution.

DOM Manipulation: TypeScript can be used to manipulate the DOM for adding or removing elements similar to JavaScript.

TypeScript is just a JS: TypeScript code is not executed on any browsers directly. The program written in TypeScript always starts with JavaScript and ends with JavaScript. Hence, we only need to know JavaScript to use it in TypeScript. The code written in TypeScript is compiled and converted into its JavaScript equivalent for the execution. This process is known as Trans-piled. With the help of JavaScript code, browsers can read the TypeScript code and display the output.

Cross-Platform:  The TypeScript compiler can be installed on any Operating System such as Windows, MacOS, and Linux.

Object-Oriented Language: TypeScript provides features like Classes, Interfaces, and Modules. Thus, it can write object-oriented code for client-side as well as server-side development.

Static Type-Checking: TypeScript uses static typing and helps type checking at compile time. Thus, you can find errors while writing the code without running the script.

Optional Static Typing: TypeScript also allows optional static typing in case you are using the dynamic typing of JavaScript.

DOM Manipulation: You can use TypeScript to manipulate the DOM for adding or removing elements.

ES 6 Features: TypeScript includes most features of planned ECMAScript 2015 (ES 6, 7) such as class, interface, Arrow functions, etc.
