title: Is that suggested to delete .map files from the build generated by ReactJS?
body: <p>I am developing large scale application in ReactJS and having a concern with huge <strong>build size issue</strong>.</p>
  
  <p>After generation of build (Production Mode) in ReactJS, I found that build size was too much heavy and after research, I got that you can <strong>delete source map</strong> files (.map) by having below configuration in <strong>package.json</strong> file. </p>
  
  <pre><code> "postbuild": "rimraf build/**/*.map",
  </code></pre>
  
  <p>Consequently, my build size got reduced by 80% which makes me more than happy.</p>
  
  <p>However, I am still having a doubt that, aforesaid is the best solution or not?</p>
