Hello, everyone 👋. I am a newcomer when it comes to JavaScript. I come from an OOP background (C# and Java). I’ve recently learned that ES6 has a class keyword that preforms similarly (but not exactly) to common OOP languages. Normally I would be inclined to use this feature in my projects; however, it came to my attention that the usage of class in JavaScript seems to be heavily discussed (mostly in a negative light). My questions to this community are:
- Should it be used often, sparingly, or be outright avoided?
- What are its advantages and disadvantages?
- Are there specific cases where the usage of
classexcels?
Please share your thoughts.
Whatever you do, I’d recommend using Typescript to give you some type safety with your JS.
I hate the heavy JS env it requires.
Adding jsdoc to standard JS makes the ide provide some type help without TS. I find that to be a good, light alternative.
The IDE support based on JSDoc is typescript (at least it is in all the ones I know about). They’re just using TypeScript’s JSDoc annotation support under the hood.
I’m not sure what you mean about the “heavy JS env” though, it’s just calling
tscin yourpackage.jsonor whatever build script you’re using (or even if none, it’s one command).I don’t have nodejs installed. That’s the heavy environment it depends on.
I think you do if your IDE is doing JSDoc-based autocompletion 😉
It’s just likely built into your IDE.
TypeScript is next on my list. The loose typing of JavaScript drives me a little nuts sometimes 😅.
In that case you will love typescript. I’m not sure what other imperative languages have both type inference and structural typing.
