Frequently Asked Questions
Why should I format my code?
Consistent formatting improves readability, reduces merge conflicts, and makes code reviews faster. Teams that enforce formatting standards spend less time debating style and more time on logic. Tip: integrate a formatter (Prettier, Black, gofmt) into your editor's save action or CI pipeline for zero-effort consistency.
What is the difference between a formatter and a linter?
A formatter rewrites code style (indentation, spacing, line breaks) without changing behavior. A linter detects potential bugs, anti-patterns, and style violations. Use both: format first (Prettier), then lint (ESLint). Tip: Prettier and ESLint can conflict — use eslint-config-prettier to disable formatting rules in ESLint.
What indentation should I use — tabs or spaces?
Both work. The industry standard for JavaScript/TypeScript is 2 spaces. Python requires spaces (PEP 8 recommends 4). Go uses tabs. Tip: configure your team's choice in .editorconfig and your formatter config so everyone stays consistent regardless of personal preference.
How do I format code automatically on save?
In VS Code, enable 'Format on Save' in settings and install the language formatter extension (Prettier, Black, etc.). For CI, add a formatting check step: npx prettier --check . or black --check . Tip: add a pre-commit hook with husky + lint-staged to catch unformatted code before it reaches the repo.
Which languages does this formatter support?
This tool supports JavaScript, TypeScript, HTML, CSS, JSON, Python, SQL, and more. Each language uses its own formatting rules and syntax highlighting. Tip: for language-specific advanced options (like single vs double quotes), use dedicated tools like Prettier (JS) or Black (Python).
