About JavaScript Minification

JavaScript minification (also known as code obfuscation or optimization) is a technique to reduce JavaScript file size by removing unnecessary characters, shortening variable names, and optimizing code structure to improve web page loading performance.

Main Compression Options

• Compression optimization: Remove whitespace, comments, optimize code structure, merge expressions：
• Variable name mangling: Replace variable and function names with shorter identifiers：
• Remove unused code: Delete unused code and dead code：
• Code optimization: Apply various optimization techniques to reduce code size：

Use Cases

• Production deployment: Reduce JavaScript file size, improve page loading speed：
• Performance optimization: Reduce network transmission time, improve user experience：
• Code protection: Increase code reading difficulty through obfuscation：
• Bandwidth saving: Reduce server bandwidth consumption：

Important Notes

• Minified code is difficult to debug, keep original source code for development
• Some compression options may affect code execution behavior, test thoroughly
• After variable name mangling, code loses readability
• Backup original code before minification
