Question 1

What is JavaScript obfuscation?

Accepted Answer

JavaScript obfuscation is the process of transforming readable JavaScript code into a version that is hard for humans to read and understand, while keeping the same functionality. It renames variables, encodes strings, and removes comments.

Question 2

Is obfuscation the same as encryption?

Accepted Answer

No. Obfuscation makes code difficult to read but does not provide cryptographic security. A determined attacker can always reverse obfuscation. Use it for casual protection, not for hiding secrets.

Question 3

Is my code uploaded to a server?

Accepted Answer

No. All processing happens 100% in your browser. No JavaScript code is ever sent to any server.

Question 4

When should I use JavaScript obfuscation?

Accepted Answer

Use obfuscation when distributing JavaScript that you want to discourage casual copying or tampering — for example, game logic, anti-piracy scripts, license checks, or commercial client-side code. Avoid it for open-source projects.
