What does obfuscated JavaScript code look like?
Obfuscated JavaScript code looks like a jumbled mess of short, meaningless variable names, encoded strings, and confusing logic — all while still working as intended by the browser.
Example:
Here’s a simple JavaScript function before and after obfuscation:
Original (Readable)
function greet(name) {
console.log("Hello, " + name + "!");
}
greet("Alice");
Obfuscated (Unreadable)

Note:
• The code still works the same.
• It's not encrypted — just scrambled.
• A determined person could reverse it, but it takes time and effort.
