What Is JavaScript Obfuscator?
Obfuscate JavaScript code to protect your source code from copying.
While minification makes code smaller, obfuscation makes it intentionally hard to understand. Obfuscation renames variables to meaningless strings, converts strings to encoded sequences, and adds control flow flattening. It is not true encryption — determined attackers can still reverse it — but it raises the barrier significantly for casual copying.
