What is Package?
A package in Node.js contains all the files you need for a module. Moudles are JavaScript libraries you can include in your project.

Every project in JavaScript whether it is nodejs or a browser application can be scoped as an npm package with its own package information and its package.json job to describe the project.

we cna think of package.json as stamped labels on those npm good boxes that our army of wombats delivers around.

package.json will be generatied when npm npm init is run to initialise a javaScript/Node.js project, with these basic metadata provided by developers:
Example:

{
  "name": "my-app",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "@testing-library/jest-dom": "^5.16.4",
    "@testing-library/react": "^13.3.0",

    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
