Exercises: Promises - Javascript In Depth
Let's go through a series of exercises to get more practice with Promises in Javascript. We look at how to resolve and reject Promises, as well as how to chain promises together in a Promise chain. We also look at how we can resolve multiple promises together using Promise.all in the bonus section.
We will see Promises show up in almost everything we do when we get to front-end and back-end web development, but it appears everywhere else as well.
This video deals with "vanilla" Promises. In a future video we'll get to async/await syntax that simplifies how we can use these promise chains.
This is part of a series where we go over Javascript in depth to learn programming concepts as well as web development: • Javascript In Depth
