Every time a module is added, Yarn creates (or updates) a
This way you can guarantee another machine installs the exact same package, while still having a range of allowed versions defined in
In npm, the
npm shrinkwrap command generates a lock file as well, and
npm install reads that file before reading
package.json, much like how Yarn reads
Other than some functional differences, Yarn also has different commands.
Some npm commands were removed, others modified and a couple of interesting commands were added.
