</head>

<script>
	var cityArray = ["Patna", "Bhopal", "Bangalore", "Mumbai", "Chennai"];

	cityArray.pop();

	console.log(cityArray);
</script>
</body>
</html>

Output:

[ "Patna", "Bhopal", "Bangalore", "Mumbai" ]

Description:

  • Removes the last element from the array
  • Modifies the original array
  • Returns the element that was removed

Remove Element by Value

<script>
	var cityArray = ["Patna", "Bhopal", "Bangalore", "Mumbai", "Chennai"];

	cityArray = cityArray.filter(function(item) {
	    return item !== "Bangalore";
	});

	console.log(cityArray);
</script>
</body>
</html>

Output:

[ "Patna", "Bhopal", "Mumbai", "Chennai" ]

Description:

  • Removes elements that match a specific value
  • Returns a new array instead of modifying the original one directly
  • The original array remains unchanged unless it is reassigned with the result

Remove Element by Index (splice())

<script>
	var cityArray = ["Patna", "Bhopal", "Bangalore", "Mumbai", "Chennai"];

	// Remove element at index 3 (Mumbai)
	cityArray.splice(3, 1);

	console.log(cityArray);
</script>
</body>
</html>

Output:

[ "Patna", "Bhopal", "Bangalore", "Chennai" ]

Description:

  • The first number represents the starting index position
  • The second number specifies how many items to remove
  • It modifies the original array directly

Summary

  • shift(): removes the first element
  • pop(): removes the last element
  • splice(index, 1): removes an element at a specific index
  • filter(): removes elements based on a condition (recommended for conditional removal)
