FAQ
What does ^1.2.3 usually match?
Under common npm semantics it allows versions from 1.2.3 up to but not including 2.0.0. See the parsed result for details.
Does this reflect the installed lockfile version?
This checks expression matching only. Actual installs still depend on the lockfile and package manager resolution.
