What is Minification
Minification is the process of removing all unnecessary characters(empty spaces are removed) and variables will be renamed without changing it's functionality. It is also a type of obfuscation .
Practical Code Example
javascript
// Minification: Strips whitespace, comments, and shortens variable names:
// Before Minification (120 bytes):
function addNumbers(firstNumber, secondNumber) {
// Add two numbers
return firstNumber + secondNumber;
}
// After Minification (32 bytes):
function addNumbers(a,b){return a+b}
