Dead Code Finder

Scans JavaScript and TypeScript source code for unused variables, unreachable statements, unused imports, and unused function parameters.

• →Paste a complete file rather than a fragment — the analyser needs full context to track references accurately.
• →Each finding shows a severity badge, the detection kind, the line number, and an explanation of why the code is flagged.
• →Try a preset from the example picker to see each detection type in action.
