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

function task1(callback){
setTimeout(() => {
console.log("Task 1 complete");
callback();
}, 2000);
}

function task2(callback){
setTimeout(() => {
console.log("Task 2 complete");
callback();
}, 1000);
}

function task3(callback){
setTimeout(() => {
console.log("Task 3 complete");
callback();
}, 3000);
}

function task4(callback){
setTimeout(() => {
console.log("Task 4 complete");
callback();
}, 1500);
}

task1(() => {
task2(() => {
task3(() => {
task4(() => console.log("All tasks completed"));
})
});
})

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

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

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

[admiralcasperr]

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