JavaScript minification is the process of compressing JS code by removing unnecessary characters like spaces, tabs, line breaks, and comments without altering the code logic.

Smaller JavaScript files download faster over mobile networks, reduce bandwidth consumption, and parse quicker in client web browsers.
