Top 3 Methods to Find JavaScript's Last Array Elements!

In JavaScript, arrays are used to store multiple values in a single variable. It is often necessary to retrieve the last element of an array. In this tutorial, we will explore different methods to achieve this.

1var fruits = ["apple", "banana", "mango", "orange", "peach"];

length property

The simplest way to get the last element of an array is to use the length property of the array. Arrays in JavaScript are zero-based, which means the first element is at index 0.

1var lastElement = fruits[fruits.length - 1]; // returns "peach"

pop() method

The pop() method removes the last element from an array and returns that element. This method changes the length of the array.

1var lastElement = fruits.pop(); // returns "peach"

slice() method

The slice() method returns a shallow copy of a portion of an array. We can use this method to get the last element without changing the array.

1var lastElement = fruits.slice(-1)[0]; // returns "peach"
