JavaScript Obfuscator is a tool designed to transform JavaScript code, making it more difficult to read and reverse-engineer while preserving its functionality. It applies techniques such as rename obfuscation, where variables, functions, and class names are altered to unreadable forms, and string encryption to conceal sensitive data within the code.
Key features include control flow obfuscation, which modifies execution paths with added logic to confuse analysis, alongside options for data flow obfuscation and anti-debugging measures that detect and counter debugging attempts. These capabilities help protect intellectual property in web applications by hindering static analysis and decompilation efforts common in reverse-engineering.
The tool supports multiple layers of protection, such as code packing for compression and encryption, polymorphism to vary code structure across builds, and virtualization to convert logic into custom machine instructions. Developers use it to safeguard client-side JavaScript from malicious tampering or theft, ensuring original intent remains hidden without impacting runtime performance.
