Should I stop using a code formatter (such as Prettier in VScode)?
There should be a setting to format only the modified lines instead of the entire file. That way, all your new code will be autoformatted but you won't have all the unrelated changes. More on reddit.com

April 12, 2021Why use prettier if ESLint can format?
Because Prettier generally does a better job of formatting than ESLint. This is for three reasons: It's really fast, particularly in comparison to ESLint. Prettier is designed to format documents and that's it, which means it can be a lot simpler than ESLint, at least architecturally, especially as there's relatively little in the way of plugins. So if you just need to format your code quickly in one chunk, Prettier is the way to go. Prettier is already preconfigured, so it's also usually quicker to get started with. ESLint has some default formatting rules IIRC, but relatively minimal ones. To ensure every detail is formatted the same way, you need to put a lot of effort into configuring ESLint, which most people don't really want to do. Related: Conceptually, Prettier formats holistically, which is to say, it takes a whole document and applies its formatting to every single syntax node - generally, this means that you get very close to having exactly one valid output, no matter how the input file is formatted. ESLint, on the other hand, not only requires each formatting rule to be configured individually, but also applies them generally individually, so it's easier to have cases where you can get inconsistent behaviour depending on the original formatting of the file.

July 27, 2022What's your approach to auto-formatting your project in VS Code?
Prettier plugin: DO NOT change any of the settings and setup a .prettierrc in your project. Set Prettier as your formatter and format on save. And then thankfully forget about formatting ever again, for you and your team. EDIT: Set your formatter with "Format document with..." > "Configure Default Formatter" More on reddit.com

r/Frontend on Reddit: Is using Prettier to format code bad.
May 23, 2023 -
Recently joined a agency as an Contract React developer. I was assigned a task to edit some inline Scss code.
Being a Prettier user I formatted the code, made the necessary changes and submitted a pull request.
Next day the senior developer reviewed my code and asked me to stop using Prettier and assigned me a task to change back the Scss code manually to inline Scss.
When I asked why should I not use prettier to format code. He said it's bad and time consuming and other team members started telling me a story how one time prettier wasn't working and started throwing errors.
That's why they never use it.
I wanted to say that It was showing error because you were doing something wrong.
Just because you once had an bad experience doesn't mean it's bad.
Plus they use one big single Scss file for the whole project.
When I question it too and asked them to use separate files and how it can effect the performance.
One team member answered it doesn't matter, how they don't care about the performance and I should be open minded and learn from them. The boss has 18 years of experience.
What should I learn why not to follow good practices!

It sounds to me though that you formatted some huge file that wasn't previously formatted with prettier (vs your own changes) And that is annoying af. Just incredibly noisy if it's a bug fix. Propose your refactor but do it outside of a bug fix.

I like Prettier, but I don't think you should unilaterally implement it in an existing codebase without discussing with your team first.

What is Prettier? · Prettier
Prettier enforces a consistent code style (i.e. code formatting that won’t affect the AST) across your entire codebase because it disregards the original styling* by parsing it away and re-printing the parsed AST with its own rules that take the maximum line length into account, wrapping code when necessary.

Formatting from the command line is a good way to get started, but you get the most from Prettier by running it from your editor, either via a keyboard shortcut or automatically whenever you save a file. When a line has gotten so long while coding that it won’t fit your screen, just hit a key and watch it magically be wrapped into multiple lines! Or when you paste some code and the indentation gets all messed up, let Prettier fix it up for you without leaving your editor.
