Frequently asked questions

How does JavaScript obfuscation work?

Obfuscation renames variables to short cryptic names, encodes strings, and restructures code to make it harder to read while preserving functionality.

Is obfuscated code completely secure?

No, obfuscation makes code harder to read but not impossible. Determined attackers can still reverse engineer it. Use it alongside other security measures.

Does obfuscation affect performance?

Slightly. String encoding and renamed variables add minimal overhead. The impact is usually negligible for most applications.
