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
