About Code Minification

      

        
Code minification is the process of removing all unnecessary characters from source code without changing its functionality. This includes:

        
    
          
  • Removing whitespace, comments, and newlines
    • 
          
  • Shortening variable names (in JavaScript)
    • 
          
  • Optimizing CSS selectors and properties
    • 
          
  • Compressing HTML structure
    • 
        

        
Benefits of minification:

        
    
          
  • Faster page loads: Smaller file sizes mean quicker downloads
    • 
          
  • Improved performance: Reduced parsing and execution time
    • 
          
  • Bandwidth savings: Less data transferred between server and client
    • 
          
  • Better SEO: Page speed is a ranking factor for search engines
    •
