title: is node.js merely a functions file that has files in it? (read the question detail for more detail)
body: <p>When I download <a href="https://nodejs.org/" rel="nofollow noreferrer"><code>node.js</code></a> from the internet through <a href="https://www.gnu.org/software/bash/" rel="nofollow noreferrer">bash</a> shell commands, am I merely downloading a "functions" folder that has many files in them, or am I downloading anything else besides that? </p>
  
  <p>This question came from the shocking realization I got when I downloaded <a href="https://angular.io/" rel="nofollow noreferrer">AngularJS</a> framework and realized it was literally a one page document and nothing more.</p>
