How to run build version using create-react-app? : <p>So, I developed a small React application using create-react-app. (I have always made applications from scratch.)</p>

<p>Then, after I was kind of happy with it, I decided to run <code>npm run build</code> to make an optimized production build. </p>

<p>Can someone please tell me how I can run the production build instead of the Dev build?</p>
