title: Confusion on the use of webpack
body: <p>I am new to JS and was learning Webpack and would like to ask some questions on it. <strong>The first question,</strong> why to use Webpack to create one bundle out of multiple JS files if we can use ES6 import&amp;export and use one script, that is, say, initially, we have three JS files: one.js, two.js and three.js.In HTML we use three scripts: </p>
  
  <pre><code>&lt;script src="./one.js"&gt;
  &lt;script src="./two.js"&gt;
  &lt;script src="./three.js"&gt;
  </code></pre>
  
  <p>Then, we use import and export which enables us to use one script like <code>&lt;script src="./one.js"&gt;</code> in HTML. <strong>The second question</strong>, why is Webpack also called transpiler? What exactly does it transpile?</p>
