Chahuadev Junk Sweeper: JavaScript and TypeScript Dead Code Diagnostics

A source of diagnostic analysis of JavaScript and TypeScript source code to identify dead code elements, created by chahuadev and updated in March 2026. It catalogs instances of unused variables, duplicate functions, and unreachable code blocks with a reported accuracy of 95%.

Use Cases

• Training machine learning models to identify 'unused variables' in source code
• Benchmarking static analysis tools against 'duplicate functions' and 'unreachable code' labels
• Analyzing 'dead imports' to optimize dependency trees in TypeScript projects

Strengths

• 95%+ accuracy in junk code detection
• Supports both JavaScript and TypeScript source files
• Includes specific labels for dead imports and unreachable code

Limitations

• Unknown record count and dataset scale
• Restricted to JavaScript and TypeScript, excluding other common languages
• Potential geographic bias toward US-based development patterns as indicated by metadata tags
