title: why are the calculator's buttons not responsive when clicked?
body: <p>I am working on a calculator project using JavaScript but the buttons are not responsive. Below is the JavaScript snippet for the equals button. What is the problem?</p>
  <pre><code>    equalsButton.addEventListener('click',button =&gt; {                              
          calculator.compute()
          calculator.updateDisplay()
      })
  </code></pre>
