title: Does ES6 module importing execute the code inside the imported file?
body: <p>Does the code inside the js file gets run during the import? if yes, then once or each time?
  e.g.</p>
  
  <pre><code>// a.js
  console.log("A");
  const a = "a"; 
  export default a;
  
  // b.js
  import a from "./a"; // =&gt; console logs?
  
  // c.js
  import a from "./a"; // =&gt; console logs again?
  </code></pre>
