# Remove duplicate JavaScript libraries
Duplicate libraries increase bundle size and memory usage, and can lead to unexpected behavior or conflicts between different versions of the same code.
## Quick Reference
- Detect and remove multiple versions of the same library
- Use a single version across the entire application
- Audit third-party scripts for bundled dependencies
## Check
Identify duplicate JavaScript libraries or multiple versions of the same library being loaded using Lighthouse or bundle analysis tools.
