Installation

You can install it as follows.

ⓘ Note

During installation, these packages are installed automatically: @eslint/js, @types/node, eslint, jiti, typescript, and typescript-eslint.

Therefore, you do not need to install these packages separately. If they are already listed in your project's dependencies, keeping them is unnecessary and they can be safely removed.
