title: How to start main index.js from my package.json file
body: <p>I have installed node.js and I have created with npm init -f my very first module.</p>
  
  <p>In created package.json file I see "main": "index.js", which should be starting point of my application.
  So in same folder I have created this file and I have putted there console.log('test')</p>
  
  <p>The problem is that I don't know how to run it without declaring "scripts": { "start": "node index.js" }</p>
  
  <p>Should I always have scripts section. Because I'm missing why there is entry point of application when I have to use scripts section anyway.</p>
  
  <p>Thanks</p>
