How to use JavaScript Minifier
The JavaScript Minifier compresses your JavaScript code by removing comments, unnecessary spaces, and formatting. This reduces file size, speeds up downloads, and improves page load performance.
What gets removed:
- Single-line comments (// comment)
- Multi-line comments (/* comment */)
- Unnecessary whitespace and line breaks
- Extra spaces around operators
- Trailing semicolons in appropriate places
Example:
Before (2.5KB):
// Initialize application
function initApp() {
// Get DOM elements
const btn = document.getElementById('btn');
// Add click handler
btn.addEventListener('click', function() {
console.log('Button clicked!');
});
}After (0.9KB, 64% reduction):
function initApp(){const btn=document.getElementById('btn');btn.addEventListener('click',function(){console.log('Button clicked!')})}
