Have you had to dig deep into linter settings? What aspects did you configure — plugins, syntax rules, auto-correction?

Yes, I have had to deeply configure linters, such as ESLint for JavaScript/TypeScript projects.

Main aspects of configuration:

• Plugins: added plugins to support React, TypeScript, Jest, and other technologies so that the linter understands specific syntax and rules.
• Rules: configured rules according to the team's coding style — enabled/disabled checks, set error levels (error, warn, off), for example, for indentation, quotes, variable usage.
• Auto-fix: enabled auto-fix capability (--fix) so that the linter could automatically correct simple formatting errors.
• Configuration: used different configurations for different parts of the project (e.g., separate settings for tests and production code).

Example of .eslintrc.json configuration with plugin and rule:

{
  "plugins": ["react"],
  "rules": {
    "quotes": ["error", "double"],
    "react/jsx-uses-react": "error"
  },
  "extends": ["eslint:recommended", "plugin:react/recommended"]
}
