While npm works just okay, Yarn ships with some improvements that give it a competitive edge over npm. In fact, developers are now migrating their Node.JS projects over to Yarn.
Firstly, Yarn dwarfs npm in terms of speed of package installation. Yarn is much faster than npm and installs packages simultaneously making it a better choice than npm.
And also, when a package is installed, a global cache is installed containing all the dependencies. This does away with the need to going back online to download them again and makes subsequent installation much faster.
Secondly, Yarn is considered more secure than npm. This is because it installs packages from the package.json or yarn.lock files.
Additionally, Yarn.lock guarantees that the same package is installed across all the devices thereby keeping away bugs arising from the installation of different versions.
