Introduction
The last element in an array refers to the element that is in the highest index position. It can be retrieved using the array’s length property which returns the number of items in the array. To get the last item, we need to subtract 1 from the length.
Here is an example:
var myArray = [1, 2, 3];
console.log(myArray[myArray.length – 1]); // Outputs 3
What is an array?
In JavaScript, an array is a variable that is used to store multiple values in a single variable. The values in an array are called elements. The elements in an array are stored in memory, and each element has its own index, which is used to access the element. Each element in an array can be of any data type, including numbers, strings, objects, and even other arrays.

The last element in an array is the element with the highest index.
How to get the last element in an array using JavaScript?
There are a few ways to get the last element in an array using JavaScript. The most common way is to use the length property of the array:
“`
var myArray = [1, 2, 3, 4];
var lastElement = myArray[myArray.length – 1]; // lastElement equals 4
“`
Another way to get the last element in an array is to use the pop() method. The pop() method removes the last element from an array and returns that element:
“`
var myArray = [1, 2, 3, 4];
var lastElement = myArray.pop(); // lastElement equals 4 and myArray now equals [1, 2, 3]
“`
Examples
There are various ways to get the last element of an array in JavaScript. Some of the most popular methods are:
-Using the length property:
var arr = [1, 2, 3, 4];
var lastElement = arr[arr.length – 1]; // gets 4
-Using the pop() method:
var arr = [1, 2, 3, 4];
var lastElement = arr.pop(); // gets 4 and removes it from the array
Conclusion
The last element of an array can be gotten in Javascript by using the .length property and subtracting 1 from it. This will give us the index of the last element in the array. We can then use this index to get the element at that position.
