JavaScript and HTML compression is the process of reducing the size of your JavaScript or HTML files by removing unnecessary characters such as spaces, line breaks, and comments. This reduces the file size, which helps with faster loading times and improved website performance.
JavaScript and HTML Compression
There are two common methods of compression:
Minification: Removing unnecessary characters from code.
Obfuscation: Making the code more difficult to read by renaming variables, functions, and properties.
Minification is more common for JavaScript and HTML, while obfuscation is often used for security or protecting intellectual property.
How JavaScript and HTML Compression Works
Whitespace Removal: Spaces, tabs, and newlines are removed to reduce file size.
Comment Removal: Comments in the code are removed because they aren't needed for functionality.
Shortening Variable Names: In JavaScript, variable names can be shortened to reduce the length of the code (e.g., renaming myVariable to a).
Reducing Code Complexity: Optimizing code so that it runs faster and takes up less space.
