What will you change or add in javascript if you have a chance?

I was asked this question in an interview sitting a couple of months ago. I'm pretty sure some of you really ever thought of changing something in JS language.

I will be happy to know your opinion in the comment.

Make it never happen in the first place :P.

Only if you did this, almost every site would break.

I would add something like the extension methods found in C#

You're removing a lot of stuff that makes JS a joy to work with

[Keff]

I agree, some of them where a bit extreme.

I also agree that some of the things like the null bug and such are a pain in the arse. But I don't think we should remove classes or force arrow function to only accept one argument. I like the freedom JS gives you, though that's also a bad thing about it :P

You might not like classes, but they have a place and can be really usefull. Not eveyone likes going all functional, to that peple I say, it's okay to be wrong xD joking, I do enjoy both

Strictly speaking, JS still doesn't have classes. It's just sugar to make it look like it does. Unnecessary really

[Siddharth]

I know XD

DATE!!!
The date and time in javascript is so messed up, the community had to create libraries for basic tasks like date and time management.
Luckily, there is a new API coming called the Temporal API. Fingers Crossed 🤞

Great update!

[Gomandev]

I agree with you @lukeshiru !

[Gomandev]

Thanks for your opinion, man!

if I had a magic wand I would make the bugs and errors in javacsript more informative so that we knew how to fix them without spending hours and days even :)

I will be much more productive if below are available:

JavaScript

• Add more data structures
  • stack, queue, heap/ priority_queue, trie, etc from c++/java/python
• Add more algorithms
  • binary_search, upper_bound, lower_bound, etc from c++/java/python
• Even shorter syntax constructs where possible
• Make things faster where possible
  • .forEach is slow most cases

Node.js

• Start execution from function main() if given, with command line args to it

[Gomandev]

Great suggestions, man. Having an inbuilt algorithm data structure will be fantastic.
