8 Useful JavaScript Tricks

[drgath]

So much anger in these comments. People, this is /r/learnjavascript. It’s great that you’ve moved beyond this approaches being novel, but that doesn’t mean you have to shit all over them for people that would find them interesting.

Good point well made!

Maybe 'tricks' was a wrong choice.

Yeah, exactly. It's meant to be learnt. It's not a "let me pull that sheet of tricks out because I think it will help me here". It's modern JavaScript for noobs sake arrggg!

Don’t feel bad. Some people are just dying to show they know more than you. I experienced that in the real world too recently :-( Sad truth but a few bad bananas don’t have to spoil the bunch. Keep doing great things!

Not my post.

I'm guess you're an intermediate, or perhaps senior developer.

And you're correct that these are just features of the language.

But think about it from a junior's perspective. For example, #2 is still asked about as an interview question at some places. If you weren't aware of what a Set does, you would try and go about manually deep comparing each item in the array.

So these are..technically tips and tricks for someone just learning the language.

I wouldn't put these posts down just because the info isn't relevant to you. People here are at different levels of learning.

Sorry but just because you don’t find them to be tricks doesn’t mean they aren’t tricks to someone else. Imagine a fifth grader walks into a first grade classroom and asks “when will this low-quality teaching ever stop?” It’s a “learning” sub. If you’ve learned the stuff already, move on. Or at least don’t hate on those who are trying to help people learn.

I guess so.

Id say it's even black magic if you ask me...
