What is a JavaScript Minifier?
A JavaScript minifier is a tool that removes unnecessary characters from JavaScript files without changing their functionality. This process reduces file size, which leads to faster loading times for websites. Minification removes whitespace, comments, and unnecessary semicolons, and often shortens variable names to make the code more compact.
