Eval JavaScript Decoder Tool
Eval Decode Logic Explained
This tool simulates what the JavaScript engine would execute when $$eval()$$ is called, without actually running the code. It captures and decodes strings passed into $$eval$$, using static analysis methods to prevent execution of harmful code.
The JavaScript $$eval()$$ function is often used in obfuscated scripts to hide malicious or complex logic. This tool safely extracts and decodes the inner code without executing it, enabling developers to audit, debug, or reverse-engineer suspicious JavaScript. It’s especially useful for security researchers, browser extension reviewers, and frontend developers working with minified scripts. Supports recursive decoding and provides syntax highlighting for better readability.
