Should I minify JavaScript?

Yes for production! Minified JS loads faster. Use source maps for debugging. Most build tools handle this automatically.

JS Minifier

Minify JavaScript code by removing whitespace, comments, and shortening code. See size comparison.

JS Input

// Calculator function
function calculate(a, b, operation) {
    // Validate inputs
    if (typeof a !== "number" || typeof b !== "number") {
        return null;
    }
    switch (operation) {
        case "add":
            return a + b;
        case "subtract":
            return a - b;
        case "multiply":
            return a * b;
        default:
            return null;
    }
}
