wtfjs VS jsfuck

Me in the interview: "Generally, no, a variable can only be assigned one numeric value at a time. However, Javascript is famous for unpredictable behaviors in variable comparison statements, for instance [] == ![]. There's actually a whole library built around documenting this type of behavior this for comedic value, and other more serious libraries geared towards solving the problem. So it's possible that some obscure variable assignment scenario would result in that line evaluating as true, but it's not something you'd expect to encounter in the real world. This has gotten a lot better with typescript and es2022, but still something you need to watch for a bit."

I do see that point of view, didn't think of that, there are some aspects of go which are a bit weird if you never touched lower abstraction languages, yet once you learn what they are, you are all set and you can code in anything. go has the least amount of gotchas I have seen in any programming language. compare it with loads of the weird stuff javascript does https://github.com/denysdovhan/wtfjs and go is like heavenly lol

Its a very poorly designed language. Its syntax and semantics are often confusing and unpredictable. There is no well defined mental model of how constructs work in this language.

WTF JS

😎 A great guide to Javascript that is both simple and wonderful, but also difficult and fun that seems like bullshit. -> wtfjs

That wasn't the point of this exercise - nobody is saying that these are actual code is examples you'd see in real life.

The point is that in lots of languages these statements would simply result in compile time errors. In JS, though, the type coercion rules are so loose (and in many cases extremely non-obvious) that you can see this head scratching behavior.

It's the same underlying behavior that leads to very cool/very insane stuff like JSFuck: https://jsfuck.com/

That's partly why, among other ridiculousness involving type, it's possible to code with only []()!+ in JS.

You forgot about JSFuck

First of all, consider security. As with any REPL, malicious actors could try to send their victims code to execute locally on their machine to whatever effect, so at least a warning is in order. Validation against such attacks is utterly useless, just take a look at JSF*ck and give up.
