What is JavaScript CALLBACK HELL? 🔥

#JavaScript #tutorial #course
// Callback Hell = Situation in JavaScript where callbacks
// are nested within other callbacks to the
// degree where the code is difficult to read.
// Old pattern to handle asynchronous functions.
// Use Promises + async/await to avoid Callback Hell

[@Ali_almughays]

[@khalidelgazzar]

Thank you! Thats helpful!

[@jhanaman04]

Thanks for the vid bro. It was helpful to actually visualize callback hell. Waiting for async/await video. I have to learn async/await.

[@BroCodez]

That's coming up after promises

If you want to execute the task one after the other why go for async, you should have used synchronous itself nah?

[@indian-shorts9215]

If you make DSA in Js that’s the thing that everybody

[@veerraptor12]

bro i love your content!!. Im a school student and my brother is a advocate, so he wants me to make a website (law firm web page) for himself so that he can receive more clients. Can u make a tutorial on that plz?? Or if u have made one plz share me the link

[@BroCodez]

I don't have a video where we build a full website together yet. I might do that in the future.

[@admiralcasperr]

Why write in JS if you aren't writing a non probable callback hell?

[@kishirisu1268]

[@alfonzo6320]
