About The Video
Check out this video to learn what promises are in JavaScript.
In JavaScript, Promises represent the eventual completion (or failure) of an asynchronous operation and its resulting value. Promises allow you to work with asynchronous code in a more manageable way, avoiding the complexities of callback functions (commonly known as "callback hell").

Key Topics Covered
Understanding JavaScript Promises: The video explains that Promises in JavaScript represent the eventual completion (or failure) of an asynchronous operation and its resulting value. They help in managing asynchronous code effectively, avoiding the complexity of callback functions (known as "callback hell").
Simplifying Asynchronous Code: Promises are designed to simplify working with asynchronous tasks, making code more readable and easier to maintain by handling success and failure states cleanly.
LambdaTest
LambdaTest is an AI-powered test orchestration and execution platform that allows you to perform both manual and automated testing across 3000+ environments, making it a top choice among other cloud testing platforms.
