FAQs
What is JavaScript formatting?
JavaScript formatting is the process of restructuring code with proper indentation, line breaks, and spacing to make it more readable and maintainable without changing its functionality.
Why should I minify JavaScript?
Minifying JavaScript removes unnecessary characters like whitespace, comments, and line breaks, reducing file size for faster page loads and better website performance.
What's the difference between beautify and minify?
Beautify (format) makes code readable by adding proper indentation and spacing. Minify does the opposite - it compresses code by removing all unnecessary characters to reduce file size.
