Typescript Basic
Introduction Random notes about TypeScript
What is TypeScript? TypeScript is a typed superset of JavaScript meaning TypeScript is JavaScript’s runtime with a compile-time type checker.
It preserves the runtime behavior of JavaScript meaning you can move code from JavaScript to TypeScript even if that the code has type errors.
Declarations var: declares a variable
let: block-scoped local variable
const: block-scoped, read-only named constant
Examples Scope Difference:
function varExample() { if (true) { var x = 10; } console.
