Why Minify JavaScript?

JavaScript minification is the process of removing all unnecessary characters from JavaScript files without changing their functionality. This includes removing whitespace, newlines, comments, and shortening variable names when possible.

Minified JavaScript files are smaller, which means they download faster and execute more quickly, leading to improved website performance and better user experience.

Examples & Use Cases

function calculateTotal(items) {
    let total = 0;

    for (let i = 0; i < items.length; i++) {
        total += items[i].price;
    }

    return total;
}

Size: 156 characters

Minified JavaScript
