About JavaScript Formatting
JavaScript formatting improves code readability and adherence to style guides. Minification reduces file size by removing whitespace and renaming variables.
Why Format JavaScript?
Consistent formatting makes code easier to understand and debug. It enforces standard coding styles (like indentation, semicolons) automatically.
What does Minification do?
Minification removes comments and whitespace, and shortens variable names (mangling), making the code much lighter for browsers to download and parse.
