About:
jscpd is a token-based duplicate code detection tool that scans source code across over 150 programming languages and formats. It identifies copy-pasted code blocks to help developers reduce technical debt and maintain code quality. Its main value is providing detailed reports on code duplication within projects or between different codebases.

Key Features:

Token-based detection for accurate duplication reporting
Configurable threshold for clone size and sensitivity
Multiple output report formats (console, JSON, XML, HTML)
Integration with CI/CD pipelines and pre-commit hooks

Use Cases:

Identifying and refactoring duplicate code during code reviews
Enforcing code quality standards in continuous integration pipelines
Performing legacy codebase analysis to assess technical debt
