Solution

Minification is the process of removing unnecessary characters (such as whitespace, comments, and line breaks) from the code without affecting its functionality.

  • Faster Loading Times: By eliminating non-essential parts to reduce file size, it is quicker to load, improving performance.
  • Bandwidth Efficiency: Reduced file sizes use less bandwidth, useful in mobile environments or for users with slower internet connections.
  • Obfuscation: Although minification is not intended as a security measure, it can make it slightly harder for someone to understand the code by looking at it, since it removes readable comments and formatting.
