165. What is the different between '^1.2.3' and '~1.2.3' in package.json

'^1.2.3' means to install the latest minor version (the middle number) of version 1. For example, if version 1.3.0 is released, it will be installed, but if version 2.0.0 is released, it will not be installed.

'~1.2.3' means to install the latest patch version (the last number) of version 1.2. For example, if version 1.2.4 is released, it will be installed, but if version 1.3.0 is released, it will not be installed.
