If you have an array, the shift function shifts everything to the left.

<html>
<body>

  <script>
    var arr = [1, 2, 3, 4]; 
    var remEle = arr.shift(); // Removed Element == 1
    
    console.log(remEle)
    console.log(arr); 
  </script>

</body>
</html>

Output:

Another way, you could also use slice(1);

slice function doesn’t change the original Array.

var myarray = ["item 1", "item 2", "item 3", "item 4"];
  
alert(myarray.slice(1));
