Should JavaScript be obfuscated?

Obfuscating your code is not a good idea. It will only inconvenience legitimate users (eg. when they need to fix a bug), and do nothing to ‘protect’ it from people who have a (financial) incentive to reverse-engineer it. It is fundamentally impossible to prevent reverse-engineering of Javascript code.

How do you know if a code is obfuscated?

Can you obfuscate code?

Programming code is often obfuscated to protect intellectual property or trade secrets, and to prevent an attacker from reverse engineering a proprietary software program. Encrypting some or all of a program’s code is one obfuscation method.

Which tool is best for obfuscation?

Tools for Code Obfuscation There are a few tools for Android Studio, such as ProGuard and DexGuard. Open-source obfuscators in Java include ProGuard, which is a class file shrinker and removes unused classes. It helps in renaming the remaining classes with meaningless names.

Can obfuscated code reverse engineer?

Obfuscation, in general, does a very good job of making it much more difficult to reverse engineer – but it doesn’t prevent it by any means. The CLR will always need to decipher the obfuscated IL, so a dedicated person can always do the same.
