The example in this article describes the use of JavaScript to use the shift method to remove the first element of the element group. Share it with everyone for your reference. The details are as follows:

In JS, we can remove the last element of the array through the pop method, and the first element of the array through the shift method

<!DOCTYPE html>
<html>
<body>
<p id="demo">
Click the button to remove the first
element of the array.</p>
<button onclick="myFunction()">Try it</button>
<script>
var fruits = ["Banana","Orange","Apple","Mango"];
function myFunction()
{
fruits.shift();
var x=document.getElementById("demo");
x.innerHTML=fruits;
}
</script>
</body>
</html>

The above code outputs the following results

Orange,Apple,Mango
