Promise
A promise in TypeScript is an object representing the eventual completion or failure of an asynchronous operation. It is a placeholder for a value that may be available now, or in the future, or never.
Syntax:
const myPromise = new Promise((resolve, reject) => {
// Asynchronous operation or task
// If successful, call resolve with the result
// If there's an error, call reject with the reason
});
A promise is typically created using the Promise
constructor, which takes a callback function with resolve
and reject
parameters. The asynchronous operation is performed inside this callback.

In TypeScript, you can use async
and await
