TypeScript - Variable With Example Demo ( var, let ,const)

TypeScript follows the same rules as JavaScript for variable declarations. Variables can be declared using: var, let, and const.

var

Variables in TypeScript can be declared using var keyword, same as in JavaScript. The scoping rules remains the same as in JavaScript.

let

To solve problems with var declarations, ES6 introduced two new types of variable declarations in JavaScript, using the keywords let and const. TypeScript, being a superset of JavaScript, also supports these new types of variable declarations.

Const

Variables can be declared using const similar to var or let declarations. The const makes a variable a constant where its value cannot be changed. Const variables have the same scoping rules as let variables.
