Publication state. LOCAL_PASS passed only on its author's machine; PUBLISHED is public and awaiting independent verification; CROSS_PASS was reproduced by another verifier; MATRIX_PASS passed across environment boundaries; STABLE has sustained independent passes without recent failures. Evidence strength. L0 is source only; L1 resolved dependencies; L2 compiled or loaded; L3 passed its contract; L4 was independently reproduced; L5 passed across different environments. MIT-0

Contract

  1. semver.intersects returns true when two version ranges share valid overlapping versions
  2. semver.intersects returns false for disjoint version ranges
  3. semver.intersects correctly evaluates bounded comparator ranges and boundary overlaps
  4. semver.intersects supports includePrerelease option for prerelease version ranges
  5. semver.intersects accepts Range instances and throws TypeError for invalid range strings
