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"

Conclusion

These are some of the ways to get the last element of an array in JavaScript. Depending on your requirements, you can choose the most suitable method. For more detailed information on JavaScript arrays, check out our Learn JavaScript course.
