Recheck is a JavaScript library for validating strings against regular expressions, offering improved safety against ReDoS (Regular Expression Denial of Service) attacks. It analyzes regular expressions to detect potential vulnerabilities, providing static analysis and runtime protection. Recheck helps developers write more secure and reliable code by identifying and mitigating problematic regular expressions before they cause performance issues or vulnerabilities in production. It's a valuable tool for enhancing application security and preventing unexpected downtime.
