JavaScript Minification Example

// This is a sample function
function calculateTotal(price, quantity) {
  // Calculate total with tax
  const taxRate = 0.08;
  const subtotal = price * quantity;
  const total = subtotal + (subtotal * taxRate);
  
  return total.toFixed(2);
}
function calculateTotal(e,t){return(e*t+(e*t*0.08)).toFixed(2)}

All processing happens in your browser - your code is never uploaded to a server.
