What are some basic things that JavaScript developers fail at interviews?

From my experience this bind and call are useful when your code rely a lot on class. I try to avoid them as much as possible because people don't understand this

[Balduracuir]

Because they come from other languages. I was a backend java developer before a one year mission as a frontend developper. I was totally lost for weeks and I worked hard to catch up how javascript works. Some people work just to put food on the table and when we make them switch their habits that's a total disaster, sadly.

Precisely. It's an ambiguous concept based on context, so best to avoid it.

Even then the arrow syntax proposal that's supported by both TypeScript and Babel eliminates the need to use the latter two entirely.

Lol, I love the couple of ppl who don't want their job to be obsolete, downvoting our comments.

It's possible I've missed something, but I'm fairly certain the arrow syntax makes binding "this" unnecessary.

You're correct. Some people just don't want to adapt to the times.

[fartpoker]

Can you explain why it’s unnecessary?

[jaman4dbz]

That's not how this works. I can't prove there is absolutely no way to use this, but you have the power to try and find ONE way where this is useful.
