Javascript Promises vs Async Await EXPLAINED (in 5 minutes)

In this tutorial I explain what Javascript promises are, why we need them, and how to use them, catch errors properly and then convert the same code to use async and await. With examples!

2:25 "Then is called when the task completes... the catch method is called if anything goes wrong". This is wrong. These methods are called immediately. It's the functions that you pass to them that are called on those conditions. This may sound like pedantry but I would strongly suggest anyone trying to learn this to fully understand the distinction here.

[@RDT]

Good catch, thanks. Pinning this comment.

[@paulhetherington3854]

Only if - there be - () call f(x) - pre amp d(x)! It never did - ught yet?

[@jellyjollyjelly9513]

"It's the functions that you pass to them that are called on those conditions. " what do you mean by "on those conditions"? do you mean the functions passed to then() and catch() are called after the task completes? im confused about this sentence

[@mattpickel223]

@@jellyjollyjelly9513 I think he is saying the method 'then' is called immediately when that line is executed. It is a method of a Promise. It binds a callback function that will be called when the promise returns fulfilled. 'The 'then' method is called when the task completes' would be wrong and should be 'The callback function passed to the 'then' method will be called when the task completes'

[@sergioadame5528]

the .then anc .catch methdos being called inmediatly ever affects something? why giving the distinction between the execition of the methods en the code inside it if nothing will happen until the promise es fullfield? i guess there is something but cant thing of a case

this is what I call a perfect 10/10 explanation. "Crisp" and at the same time complete information with example.

[@omdodmani3205]

Yeah! Example Makes it way easier to understand compared to just explaining the theory.

[@SoraJustAGuy]

It’s important to point out that working with multiple apis you often have to chain multiple promises resulting in callbacks nested inside callbacks nested inside callbacks nested inside callbacks…you get the idea. 😅This is what we call a CALLBACK HELL. So the primary reason async/ await exists is to avoid a callback hell

[@RDT]

Absolutely 👍🏻

[@miladevs]

Great analogy with the waiter bringing coffee to explain promises! It really clarifies how promises work in JavaScript. Using then and catch makes handling asynchronous operations much cleaner. Thanks for breaking it down so well, Kyle!
