title: Merge multiple minified javascript files in recursive folders into one file
body: <p>I have multiple minified files in multiple folder in a single folder for minified js.</p>
  
  <p>I wish to create single js file from all of minified js. 
  Now I am using type command to concatenate all files like </p>
  
  <pre><code>type .\\v2\\dist\\js\\*.js &gt;&gt; .\\build\\a.min.js   &amp;&amp;   type .\\v2\\dist\\js\\config\\*.js &gt;&gt; .\\build\\a.min.js &amp;&amp; ... 
  </code></pre>
  
  <p>Like wise I need to append all recursive folders.
  Is there any clean way to do it.</p>
  
  <p>Please don't suggest using Gulp or Grunt as we are already in process of removing them &amp; using Webpack. Any code using webpack or using npm or simple command line is welcome.</p>
