What's the difference between a tilde (~) and a caret (^) in the package.json file?

^ include everything greater than a particular version in the same major range.

~ include everything greater than a particular version in the same minor range.

Allow or disallow changes

• Pin version:1.2.3.
• Use ^(like head). Allows updates at the second non-zero level from the left: ^0.2.3 means 0.2.3 <= v < 0.3.
• Use ~ (like tail). Generally freeze right-most level or set zero if omitted:
• ~1 means 1.0.0 <= v < 2.0.0
• ~1.2 means 1.2.0 <= v < 1.3.0.
• ~1.2.4 means 1.2.4 <= v < 1.3.0.
