 - To lint the code, **you need to run the `lint:fix` script**
 - To transpile source code to `javascript` we use [NCC](https://github.com/vercel/ncc). **It is very important to run the `build` script after making changes**, otherwise your changes will not get into the final `javascript` build
 
-> [!TIP]
-> Instead of running each script individually, you can run the aggregate scripts:
->
-> - `npm run fix` — formats, lints (with autofix) and rebuilds the `dist/` bundle.
-> - `npm run check` — runs the same validation as CI: `format-check`, `lint`, `build` and `test`. **Run this before pushing a pull request** to make sure it will pass the required checks.
->
-> Git hooks are installed automatically when you run `npm install` (via [husky](https://typicode.github.io/husky/)):
->
-> - a **pre-commit** hook formats and lints staged files with [lint-staged](https://github.com/lint-staged/lint-staged);
-> - a **pre-push** hook rebuilds `dist/` and runs the test suite.
-
 **Learn more about how to implement tests:**
 
 Adding or changing tests is an integral part of making a change to the code.
