Healthy across the board
Permissive license, no critical CVEs, actively maintained — safe to depend on.
Has a license, tests, and CI — clean foundation to fork and modify.
Documented and popular — useful reference codebase to read through.
Scorecard "Branch-Protection" is 1/10; 8 cyclic import chains — pervasive coupling
- ⚠Scorecard: default branch unprotected (1/10)
- ✓Used by 5 trusted projects: vercel/next.js, remix-run/remix, vercel/turbo +2 more
- ✓Last commit 1d ago
- ✓29+ active contributors
- ✓Distributed ownership (top contributor 26% of recent commits)
- ✓MIT licensed
- ✓CI configured
- ✓Tests present
What would improve this?
- →Deploy as-is Mixed → Healthy if: bring "Branch-Protection" to ≥3/10 (see scorecard report)
Maintenance signals: commit recency, contributor breadth, bus factor, license, CI, tests + OpenSSF Scorecard
trekhleb/javascript-algorithms →
Healthy across all four use cases

Has a license, tests, and CI — clean foundation to fork and modify.
Documented and popular — useful reference codebase to read through.
No critical CVEs, sane security posture — runnable as-is.
