After I upgraded to the latest stable node and npm, I tried npm install moment –save. It saves the entry in the package.json with the caret ^ prefix. Previously, it was a tilde ~ prefix.
Why are these changes made in npm?
What is the difference between tilde ~ and caret ^?
What are the advantages over previous ones?
See the NPM docs and semver docs:
~version “Approximately equivalent to version”, will automatically update you to all future patch versions that are backwards-compatible, without incrementing the minor version. ~1.2.3 will use releases from 1.2.3 to < 1.3.0.^version “Compatible with version”, will automatically update you to all future minor/patch versions that are backwards-compatible, without incrementing the major version. ^1.2.3 will use releases from 1.2.3 to < 2.0.0.See Comments below for exceptions, in particular for pre-one versions, such as ^0.2.3
