Does obfuscation make JavaScript secure?+
Obfuscation is a deterrent, not true security. A determined attacker with sufficient time can deobfuscate any JavaScript. Never embed sensitive secrets (API keys, passwords, private keys) in client-side code - obfuscated or not. Use server-side validation for all security logic.
What is the difference between minification and obfuscation?+
Minification removes whitespace and shortens names for smaller file size while keeping code readable. Obfuscation intentionally transforms code to be unreadable, using techniques like string encoding, control flow flattening, and dead code injection.
Will obfuscated code run slower?+
Slightly. Obfuscation techniques like control flow flattening and string array encoding add runtime overhead. The impact is usually negligible for most use cases, but avoid obfuscating performance-critical loops.
Can I obfuscate TypeScript or JSX?+
Compile to plain JavaScript first (tsc or Babel), then obfuscate the output. This tool works on plain JavaScript - transpile before uploading.
