165. What is the different between '^1.2.3' and '~1.2.3' in package.json
This is the SemVer notation.
^
symbol shows that we can use any version equal to or higher than the current minor (middle number) version. No higher in the major.
For example ^1.2.3
allows to use versions 1.2.3
, 1.2.4
, 1.3.1
but not 3.0.0
~
symbol stays to accept only patch changes (last number) in the version. Not higher for major or minor.
For example ~1.2.3
allows to use versions 1.2.3
, 1.2.4
, but not 1.3.1
or 3.0.0
See references: Semantic versioning, npm semver calculator
