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.

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!

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.

Ohh yeah, I'm aware.. I agree that they are kinda unnecesary, but they make my life a bit easier. I fricking hated constructor functions, but now I kinda enjoy working with "classes". I prefer not to if I can, but sometimes I need to

Couldn't we also consider that high-level programming languages are also just sugar?

[Keff]

One of the things I like about arrow function is that, you don't need to fill your code with the function keyword, reducing the amount of noise and clutter. I really enjoy those kinds of things, where you don't need to write unnecesary keywords. Take Java for example, a big percentage of the code is just public, private, final, static... I don't enjoy that, it's a mess (but they have a place and I can see the value of them).

And although I would not like this change to be implementet, I get your point :P

I'm willing to bet folks will like JS to be even more class heavy

Let's hope it does not go that way, at least not excesively 🤞

I guess everyone is welcome to imagine the ideal JS for them 😄

Of course, that's what I like about this types of posts, they make us talk about this things and respectfully debate them

Even in pure functional languages like Haskell, there are things like classes. Sometimes classes even enable more elegant functional designs. Sure people abuse OO horribly, but removing classes from the language entirely is too dogmatic.

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

[Taufik Nurrohman]

Rename XMLHttpRequest with XMLHTTPRequest.

[Timothy Foster]

change it to be from "location" import { thing }

Now that you mention it, I never realized how much I wanted this syntax until now.

[Valentin Boettcher]

Make it never happen in the first place :P.

I cringe reading this. You want to remove mostly optional stuff to make JS more like other language. My guess is you don't want to use JS and really want Python support in browsers.

[insidewhy]

No you can't, not when private data has to be encapsulated into a struct like concept, not unless you're willing to sacrifice a great deal of performance and memory.

I think you're being too dogmatic.
