body: <p>I am new to Node Js and Express js, and i need to implement fucntionality like call second api after first api execution completed and call second api with the response of first api.</p>
  <p>It's just a demo, API counts can be 100 or 200, but i need to implement Dynamically in node js.</p>
  <p>How would i approch this?</p>
  <pre><code>// 1st API
  api.get(/one, (req, res) =&gt; {
       res.send('Hello')
  })
  
  // 2nd api
  api.get(/second + one, (req, res) =&gt; {
        res.send('world')
  })
  
  </code></pre>
