Editing NodeJS (section)

====package.json====
<code>package.json</code> holds important information about a project. It contains human-readable metadata about the project (like the project name and description) as well as functional metadata like the package version number and a list of dependencies required by the application. It is used by the npm CLI (and yarn) to identify your project and understand how to handle the project's dependencies. It's the  file that enables npm to start your project, run scripts, install dependencies, publish to the NPM registry, and many other useful tasks.
The scripts sections defines the commands which could be used by
 npm run <SCRIPT> 
e.g.
  "scripts": {
    "ng": "ng",
    "start": "ng serve",
    "build": "echo 'create build timestamp' && node ./src/environments/createBuildTimestamp.js && ng build",
    "watch": "ng build --watch --configuration development",
    "test": "ng test"
  },
oddly enough some scripts can be called directly by <code>npm <SCRIPT></code> but not the build script.
