JavaScript DeObfuscation:

JavaScript DeObfuscation is the technique used to encode JavaScript code and make it unreadable by a human.

JavaScript DeObfuscator:

JavaScript DeObfuscator or JavaScript unpacker is one of the best tools found on this website and it is used to decode, unpack or deobfuscate javascript code.
