In addition to npm, there is this package management tool

Speaking of package management tools, npm is the most familiar to everyone. In addition to it, there is yarn. I believe you must have heard of it. Next, let's take a look at what yarn is and how to use it.

1. What is yarn?

Yarn is a package manager for your code. It allows you to use and share (such as JavaScript) code from developers all over the world. Yarn can complete these tasks quickly, safely, and reliably, so you don't have to worry about it.

Through Yarn, you can use other developers' solutions to different problems to make your own development process easier. If you encounter problems during use, you can report them or contribute solutions. Once the problem is fixed, Yarn will update to keep in sync.

Code is shared through packages ( or modules) . A package contains all the code that needs to be shared, as well as the file describing the package information, called package.json .

2. Installation

There are three ways to install Yarn on windows system,

2.1 Download the installer
