Can I validate package.json and config files?

Question 4

What's the difference between beautify and minify for JSON?

Beautifying JSON adds proper indentation and line breaks, making it human-readable for debugging and development. Minifying removes all whitespace to reduce file size for production APIs and data transfer. Use beautify for development, minify for optimized production payloads.
