Frequently Asked Questions
What is the difference between ^ and ~ in npm versioning?
`^1.2.3` permits updates that do not modify the leftmost non-zero digit (`1.2.4`, `1.9.0`), whereas `~1.2.3` only permits patch-level updates (`1.2.4`, `1.2.9`).
How are pre-release tags ordered in SemVer?
Pre-release versions have lower precedence than their normal release (e.g., `1.0.0-alpha < 1.0.0-beta < 1.0.0`).
