2. Run JSCPD with appropriate options
3. Review the reported duplicates
4. Refactor duplicate code to improve maintainability

Supported Languages

JSCPD supports detection in languages like JavaScript, TypeScript, Python, Java, C++, and more. It analyzes source code files and reports duplicate blocks based on token sequences.
