Why is Yarn faster than NPM?
There is no doubt that Yarn works much more efficiently during installation. The NPM first tracks all branches of dependencies and then receives the required packages. But Yarn doesn’t. It first searches for dependencies in the registry. It then receives the downloaded packages from the cache directory. If it finds a dependency, it uses it, if not, it downloads it as tar. Finally, it copies all packets from the global cache to the node_modules directory.
All these operations are performed in parallel to increase the installation speed. Using a global cache is much faster than downloading all the packages every time we need them. Yarn also has an added advantage: it allows Yarn to work offline!
Conclusion
In this article, you have learned how to install Yarn on Ubuntu. Except for this ability, now you clearly know that Yarn is much better than NPM. From now on you are ready to use this tool and enjoy its features.

*- Yarn does not work with node.js version older than 5
What is the difference between NPM and Yarn?
Yarn differs from npm in several major ways. First of all, Yarn stores all installed packages. Yarn installs packets simultaneously, which is why Yarn is faster than NPM. Both load packets from npm tanks. Yarn generates a package from yarn.lock to lock dependency versions by default. In contrast, npm provides the CLI shrinkwrap command for this purpose.
Please name some of the main advantages of Yarn over others.
