Error handling Promises in JavaScript - Fun Fun Function

Today, we’re exploring error handling! We’re going to talk about how you shouldn’t swallow errors by doing crash reporting inside of functions. Instead, we’re going to look at how you can let errors propagate up to the interface by making use of promises.

I love these "You're doing it wrong. Here's the better way" episodes. I find they are more pertinent to more advanced viewers who already know how promises work and are more representative of the real world.

Thank you a lot for making this content MPJME.
I was abble to pass through a technical interview because one of your videos, so THANK YOU SO MUCH!

The freedom to return and compose Promises is what made me fall in love with them. Thanks for sharing, and I concur with earlier commenters... let's see a deeper dive on this!

YouTube just recommended your videos to me, and i'm absolutely hooked! Funny content while still managing to explain difficult concepts very well, i'm somewhere between laughing my ass off and getting up in the middle of the night to write some code!
Keep up the good work

Oh, and awesome music too

It's been a while since I've watched your videos (just not enough time in the day) but I was pleasantly surprised with the production value of this one. I love the new opening sequence and the way you handle the picture-in-picture when your face is on screen. Just wanted to say keep up the good work!

'standardJS hippie' - i laughed quite a bit! :D

that french press scene was awesomely over the top! love it

This is one of the reasons I love golang. That is because errors are just values, they propogate, and wrap nicely for returns etc. and functions can return multiple values directly so they are easy to return.

I love the intro! Please don't change.

[Arvigeus]

Very uninformative and misleading video. This is not the proper way to make a coffee! (the Promise stuff was good as usual)

[jonathansilva]

You've got my like even before the content begins... Just for that intro with the coffee. Hahaha

[dusnoki]

Awesome video man. I too was making the same mistakes with promises in the past... glad I'm not the only one :D

[matthiasmuller]

Very interesting topic. Would be great to see further, more sophisticated episodes about error handling in the future.

[muxahuk]

I would also mention a practice, where you make some logs/notifications in catch, but still throw error to the caller.
Promise.reject('some error').catch((e) => { doLogging(e); throw e; });
this can be usefull and u steal return promise with error to the "ui" component.

I hope we keep this opening for QUITE a while it's so exciting XD <3

[Patrick-yuet]

Awesome song, very nice production and teaching!!!!

[FelipeOliveiraCarvalho]

Hello @mpj! Thank you so much for making this video. :-)

"screw you, you standard JS hippie" 😂

[jasoni]

Ha, I'm patron 1000. I just had to see it jump past 999. Uhhm, you videos are good also.

[PapaLazarou]

You should make a video on a good way of handling errors from multiple queued promises
