What is type assertions in typescript?..

Answer / Nitish Bhardwaj

Type assertions in TypeScript are used to explicitly define the type of a value. You can use them when TypeScript's type inference fails or when you know more about a variable than what TypeScript infers. There are two ways to do this: 1) Using the 'as' keyword, for example: `let myVar = document.getElementById('myId') as HTMLDivElement`. 2) Using the '!' keyword to assert that a value is not null or undefined, for example: `let el = document.querySelector('#myId')!;`
