You can use pop() at the simplest level to get the last element only and assign that value as an array to the original array. Unlike splice you do not need to worry about calculating the length value of the array.

var fruits = ["Banana", "Orange", "Apple", "Mango"];
fruits = [fruits.pop()];
console.log(fruits)

**Notice** This returns the last element and removes it from the original array – Sebastian Kaczmarek Apr 05 '19 at 11:40
Well, I see two possible issues with this solution: 1) your result is an array containing the last element of fruits instead of just the element and 2) by using pop() you will remove the last item from the array, which is not always desirable. – Bart Hofland Apr 05 '19 at 11:40
@BartHofland that what OP needs `I have a list of array I only need last element in array` which means he needs only last element to survive in array – Ankit Agarwal Apr 05 '19 at 11:41

Correct. THe last element. Not "an array with the last element". – Bart Hofland Apr 05 '19 at 11:41
@BartHofland again see OP clarifies here `My Required result is ["Mango"].` `Mango` is inside an array – Ankit Agarwal Apr 05 '19 at 11:42
Ah. I see your point. His question is a bit unclear. Does he wants the last element in an array or the last element in the array... – Bart Hofland Apr 05 '19 at 11:42
Yes, you are correct. My apologies. – Bart Hofland Apr 05 '19 at 11:42
@BartHofland that is fine. I admit it is quite confusing – Ankit Agarwal Apr 05 '19 at 11:43
@all Thanks But for your response. I got my desired output by fruits.splice(0,fruits.length-1) – Gaurav Kandpal Apr 05 '19 at 12:04
@AnkitAgarwal it's fine. I mentioned it in case OP would be surprised why the original array is changed or his code would behave weirdly because of that. Treat it as an extension of your answer, not as a correction. Cheers! – Sebastian Kaczmarek Apr 05 '19 at 12:56

You can access it with his index and the array length

var fruits = ["Banana", "Orange", "Apple", "Mango"];
fruits = [fruits[fruits.length-1]];
console.log(fruits)

You can access last index of array by getting array length and accessing last index.

var array = [1,2,3,4,5,6];
var val = array[array.length - 1]; // 6

This is another way you can get last index:

<html>
<head>
<title>Get the last element in an Array</title>

<script language="javascript" type="text/javascript">
<!--

var x = new Array(2,3,4);

alert(x[x.length-1]);

//-->
</script>

</head>
<body>

</body>
</html>

You could take Array#slice with a negative value, from the end, and return an array of the last item.

Slicing does not mutate the original array.

var fruits = ["Banana", "Orange", "Apple", "Mango"],
    wanted = fruits.slice(-1);

console.log(wanted);

You can get the last element of an array with the following methods:

1st:

var fruits =  ["Banana", "Orange", "Apple", "Mango"];
var fruits = fruits.slice(-1)[0];
console.log(fruits);

2nd:

var fruits  = ["Banana", "Orange", "Apple", "Mango"];
var fruits = fruits[fruits.length-1];
console.log(fruits);
