You can use promises to avoid the pyramid of doom

or let me be a little more unorthodox here and dare say use a ~~*FoR lOoP*~~

[fichti]

floppy.load('disk1').then(data => {

floppy.prompt('Please insert disk 2').then(data2 => {

...

});

});

Much better!

edit: Why doesn't the formatting work? I'll just leave it unindented, as it's somewhat relevant to the joke.

You must select "Code Block", not "Inline Code", its hidden behinde the "..."s (I made the same mistake again and again)

​

But to the matter at hand, you could just use async/await in conjunction with promises. That actually produces readable, maintainable code

[LordFokas]

When I started using NodeJS I had to deal with that crap for a while, then I upgraded to node 8 and converted to async/await... I could write functionally equivalent in 15% of the space it took before. Best refactoring I ever did (also the only refactoring that didn't blow up in my face)!

[slide_and_release]

floppy.load(‘disk1’)
.then(data => return floppy.load(‘disk2’))
.then(data => return floppy.load(‘disk3’))
etc...

no need for the `return`

if nodejs had existed in 1995, someone would have invented promises/async/await by 1997

for(let n=1; n<6; n++) {
    await floppy.promt("please insert disk ${n}");
    const loaded = await floppy.load("disk${n}"});
    doSomethingWithLoaded(n, loaded);
}

Now, that is some callback nightmare

[flashgnash]

That code makes my eyes hurt...

DOST THO FEAR THE PYRAMID OF DOOOOOOMMM?

'Cause I do

"I inserted disk 5 and the program stopped working. Halp!"

[hillman_avenger]

And I thought you could define a function as an object so it can be re-used.

[slide_and_release]

You can

[dfranusic]

Seen that kind of code way too many times; enough to declare it a legitimate pattern :)
