Why Typescript over Javascript

If you are a beginner, than You can consider Typescript as a superset of a javascript.. more specifically it can be considered as a typed superset of javascript. An example below shows basic representation of difference between Js and Ts.

**Syntax Difference in JS and TS
// javascript

var x = 10;
let y = “Hello”;
const z = true;

// typescript

let x: number = 10;
let y: string = “Hello”;
const z: boolean = true;

As the name suggests, Typescript is a statically typed programming lanaguage whereas Javascript is a dynamically typed programming language.

Reasons to use Typescript over Javascript
Static Typing : TypeScript introduces static typing, allowing you to define types for variables, function parameters, and return values. This helps catch potential errors at compile-time rather than runtime, making the code more robust and less error-prone.

Code Readability and Maintainability : Typescript allows developers to write readable , run-time error prone , code for large code bases and projects.

Early Error Detection: TypeScript’s static type checking helps identify potential issues early in the development process. This can lead to more stable code and reduce the likelihood of bugs making it to production.

Interfaces and Enums: TypeScript supports the use of interfaces and enums, providing a way to define clear contracts for the structure of objects and representing sets of related values. This can contribute to better code organization and understanding.

Overall, it totally depends on the project requirement and the length of the project . If the project size is too large then consider going with Typescript :)
