JSFuck is an esoteric JavaScript library that encodes and executes arbitrary JavaScript using only six characters: []()!+. It works both in browsers and Node.js and is primarily educational and obfuscation-oriented.
Use cases
- encode javascript into only six characters
- obfuscate javascript source code
- study javascript type coercion and internals
- demonstrate esoteric programming techniques
- test javascript parser and sandbox robustness
When to choose
- you need extreme javascript code obfuscation
- you want to teach or explore javascript coercion quirks
- you are building security tests around eval and code injection
When to avoid
- you need readable or maintainable code
- performance matters since output is massively inflated
- you need real obfuscation guarantees rather than novelty
