title: Node.js project with no package.json
body: <p>Is it ok to have a node.js project with no package.json? The ones I see on the internet all come with package.json</p>
  
  <p>What is the effect of having no package.json?</p>
  
  <p>How is package.json created in the first place? Is it created automatically? I am wondering why I do not have package.json</p>
