Minification removes unnecessary characters from code files without altering functionality. Smaller file sizes decrease bandwidth consumption, speed up page load times, and improve overall Core Web Vitals performance.

Does minification break my code execution?
Safe string replacement logic strips whitespace and comments without modifying variable names or execution behavior.
