package.json version example

Example 1: npm version notation

1.2.3 => 1.2.3 (Matching exactly same version)
~1.2.3 => >=1.2.3 && < 1.3.0 (Matching minor version)
^1.2.3 => >=1.2.3 && < 2.0.0 (Matching major version)

# From 1.0.0 -> 1.0.1

# From 1.0.1 -> 1.1.0
npm version minor

# From 1.1.0 -> 2.0.0
