title: Javascript send value from one file to another file
body: <p>Sorry for my English. I am wondering whether it is possible to send one file to another file variable?</p>
  
  <p>for example</p>
  
  <p><strong>oneFile.js</strong></p>
  
  <pre><code>var a = true;
  </code></pre>
  
  <p><strong>twoFile.js</strong></p>
  
  <pre><code>if(a == true) {
  alert("hellow");
  }
  </code></pre>
