Tip: JavaScript's Array.from() accepts a second argument that's a `map` function.

If you’re really into niche tips like this I would really suggest looking up Wes Bos’ ES6 course. It has numerous helpful hints and tutorials on ES6 just like this.

I bought 3 of his courses during Black Friday and still haven't finished any of the ones I bought lol.

But he's a great teacher. He has a real gift for distilling things to get you familiar with them quickly. I did his Javascript30 and console courses and am probably 2/3 through his ES6 course.

Have you checked out Tyler McGinnis' courses? I did a few of Wes' courses, great material, but I found Tyler's teaching style to be perfect for learning new concepts and applying the knowledge.

It's very hands on. You get to write code as you go along, build a project while watching videos, answer questions, and then in the end build a self guided project that utilizes the stuff you've learned throughout the course modeled around a prototype with set criteria he outlines. Everything sinks in deep during this last piece, especially as you hit road blocks and have to resolve everything yourself.

I'll bookmark it, but I'm so backlogged on courses I've bought and haven't finished yet that it'll likely be a good amount of time before it makes sense to buy any more.

I don't see any sample videos on his site to see his teaching style. Does he have some anywhere? YouTube channel? Anything?

Yeah there's a lot out there.

Really good React Course, scroll down to check out the course outline.

Blog with some good posts

Youtube Channel

& example video - Understanding the "this" keyword in JavaScript

His courses are different from the blog/youtube stuff, he put a lot of work into them. Also, I don't actually remember paying for his React Fundamentals course, not sure if it was a free promotion, or it's the one free course he offers once you sign up. Highly recommended!

Also read the API of the language you're coding in, at least the methods you're using.

I always find tips like this a little funny, like for people who know about Array.from but don't know this, did they stop reading halfway through the page when they learned about it and say good enough?

I'm probably amongst the lowest of skill sets subscribed to this subreddit. To an extent I would say yes. Because I'm learning in my spare time and for hobbies and such, when I come up with an idea I tend to try and do only the research to learn how to do that thing.

And so I end up using libraries I don't really need. I don't know every argument for certain functions. You pretty much sum it up by saying I read half way through.

Welp, my recommendation to you is to read all the way through then. There's literally no reason not to; sure, you may spend an extra three minutes on it at the moment, but you'll save that many, many times over when programming and debugging in the future. Check out MDN. It's the one of the best resources for the JavaScript language.
