What is the Importance of NPM?

A treasure chest that is full of tools and options for JavaScript developers. It plays a pivotal role in the world of JavaScript as it helps create ready-made code from tiny helpers and big frameworks. NPM saves a lot of time and effort during the creation of building websites and applications. It has become a beacon of hope for developers as it allows them to quickly add features, fix minor bugs, and improve their projects with just a single tap.

Building Blocks of NPM

Registry: A vast dimension of the library where the JavaScript codes (packages) are stored. To make your project a successful one, you can find all sorts of codes in one place.
Command Line Interface (CLI): Perhaps, a great function that allows you to spin the magic wand and perform any tasks without difficulties. You can ask NPM to do things like “install” or “publish”. You can add new codes to your project or share codes with others.
json: The job of such components is to tell NPM what your project needs to work correctly, like which packages it depends on and what scripts to run.
Package Lock File: Everything remains consistent as it works as a checklist that NPM uses to ensure that every project always works accurately. It keeps track of exactly which versions of each package your project is using
