title: What exactly is the 'react-scripts start' command?
body: <p>I've been working with a React project using <code>create-react-app</code> and I have two options to start the project:</p>
  <p><strong>First way:</strong></p>
  <p><code>npm run start</code> with the definition at the <code>package.json</code> like this:</p>
  <p><code>&quot;start&quot;: &quot;react-scripts start&quot;,</code></p>
  <p><strong>Second way:</strong></p>
  <p><code>npm start</code></p>
  <p>What is the difference between these two commands? And, what is the purpose of the <code>react-scripts start</code>?</p>
  <p>I tried to find the definition, but I just found a package with this name. I still don't know what is the use of this command?</p>
