title: Check if an array is empty or not - Postman - node.js
body: <p>I am getting the response in this format:</p>
  
  <pre><code>{
      "test1": [],
      "test2": [],
      "test3": [],
      "test4": null,
      "test5": []
  }
  </code></pre>
  
  <p>After sending a request, this is the response i get.</p>
  
  <p>And i want to check f. ex. does <code>test1</code> is empty or not.</p>
  
  <p>And if it is empty it's enough to just console log.</p>
