It is recommended. But in TS it is not necessary with rare exceptions.
That’s what’s really irks me be about JS–you can do just about whatever but you’re not supposed to.
It’s an imperative language, but best practices are to use it functionally.
You can omit semicolons, but best practices are to use them.
You can use sloppy equality, but best practices are to always use strict.
After switching to typescript with linting and prettier I simply hate writing vanilla JavaScript anymore. Some people complain about the extra project setup needed but I find that time pays for itself immediately.
Extra project setup like
pnpm add -D typescript && tsc --init? One thing that is kinda annoying is that you have to manage were will js files go.And eslint and setting up tsconfig for your project structure.
You don’t need eslint with TS.
Why do the typescript extensions to eslint exist then?
I don’t know. I never used eslint, therefore it is not needed. Everything works perfectly fine without it.
Why do you need it?
Same reason you use typescript. It helps you catch bugs and follow programming best practices. You also don’t need typescript, but with it your code is better. Typescript is technically just a really fancy linter. The actual compilation mainly just removes the type data and does some JavaScript engine compatibility.
JavaScript reminds me of an older brother who happens to be the most laid back stoner you could meet. “Like yea man, you should probably use semicolons, but I ain’t gonna narc”
I wouldn’t do it without an auto formatter. With prettier it will catch potential no semi colon issues.
You absolutely have to use prettier with JS. I don’t think there is auto adding missing semicolons in C/C++ though, it would be very useful.
I tried prettier and I thought it was literally making my code uglier. It’s eslint --fix for me.
thanks to eslint enforcing it in the default rules it’s necessary for most typescript projects
Except that you should use Prettier for formatting instead of ESLint. That said, semicolons are useless noise
Never used eslint. prettier is a must. semicolons are only needed to split some rare TS syntax lines.
Yes, true. I also did setup so that any missing semicolon will be added, because I got sick of not inserting them sometimes and then some code was without them and some was. (Before I tested just leaving them all out, out of fun, so I got into the habit of just leaving them out regularly)
