Basically you made Javascript looks like Golang Lol.

My life is pretty dull and uneventful, so this was the best 45 seconds of my life.

Congrats! You one step closer to using monads for error handling

I've been asynchronously awaiting for this and finally this video showed up

And we're coming full circle.

Holy shit, most youtubers would have turned this into a 10 minute monetized video. You are amazing.

This reminds me of a quote:
"Errors are values"

rust developers can just put ? in front of the function. If an error occurs, the function halts and returns the error. It's awesome for those that understand it, a nightmare for someone unfamiliar with rust lol.

And then you will end up with tower of ifs, when each function depends on previous results
You've just writed try catch using if statements nothing changed
What you can do is catch them all together
And make specific errors for each function and then switch through errors in catch block if you need to perform something for each error case

Swift just got Async/ Await feature and now I'm getting this as recommended.

The difference is honestly astounding. I want to get better at writing clean JavaScript code thanks.

Such a quality of life improvement. I read this in an article once, when I was just starting out, and started writing it, just waiting for the other shoe to drop (I had to defend it before my boss, who was skeptical at first, even though he hated try catch and longed for the async.js days); cause why wasn't everyone doing this? No regrets!

Tips:
- Make the function take a promise as a parameter
- use "catch" method of the promise
- Call this function "to"
function to (promise) {
return promise.then(data => [null, data]).catch(err => [err])
}
const [err, data] = await to(fetch(/*thatUrl*/))
Notes: Dont need to have an async function or to use try-catch; its reusable for any function returning a promise; its a oneliner in a oneliner \o/

I'm starting to love programming. I enjoy it now. I understand it now.

Looks a lot like Andrei Alexandrescu's "Expected<T>" from his 2012 talk. It's a variant that stores either the value, or an exception. But C++'s operator overloading makes it more convenient to use.

Return error as value is amazing. I love Rust.

Absolutely love the conciseness
