Agreed, but sometimes practicing this type of coding style in easier task make it easy on harder tests with a max char length

Minified code is not optimal for reading ^_^

From MDN:
NEVER USE eval()!
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/eval#never_use_eval!
:)

Using eval may cause JS-engine not to use some optimizations on compilation stage.

I guess not (depending on the complexity of the operation), but in this case, yes.

huuu..m

(check mine)

I'd like to know as well

how do you delete a kata?

understood, I will remove this kata.

Can you explain how this works?

agree.

You wouldn't really go for it in a real world, this is just a kata.

Eval isn't necessarily a bad practice by the way, it is very dangerous, but still, it's a feature of the language and there are situations where you have to use it. So, even in a real world scenario, if you can control what's gong to be eval(uated), then I don't really see anything wrong in using it.

isn't eval a bad practice?
