Check JavaScript for common mistakes, risky browser APIs, debugging statements, loose equality, suspicious assignments, hard-coded secret candidates, and maintainability warnings without running the code.

Processing is performed locally. Advanced language edge cases may require a full standards-based parser or project-specific toolchain.
Input:
function render(value) {
document.getElementById("result").innerHTML = value;
if (value = "admin") { console.log("Admin"); }
}Output: Run the included example to see a real result generated by this tool.Run the checker to scan for suspicious assignments, loose equality, debugging statements, and structural imbalances.
The security scan lists innerHTML, outerHTML, insertAdjacentHTML, and document.write occurrences with line numbers.
Conditional expressions containing a single assignment operator are reported as possible mistakes.
This tool provides a lightweight pattern-based review but does not replace a full parser or ESLint configuration.
Long token-like strings assigned to key, token, secret, or password names are flagged as candidates for manual review.
