NPM stands for Node Package Manager which is a package manager for nodejs.It have the CLI tool that helps us to install, manage, and remove Node.js packages.Moreover npm is the world's largest Software Registry. The registry contains over 800,000 code packages. Open-source developers use npm to share software. Many organizations also use npm to manage private development.

WHAT IS YARN?

Yarn is introduced by the facebook in 2016 as a replacement of npm.It was developed with an objective to offer more advanced features that npm doesnot have and create a more secure, stable, and efficient product.

installed.
YARN - yarn is installed using npm.

2.LOCK FILE
