How to Split a String and get Last Array Element in JavaScript

When you are working with strings with a repeated pattern like a comma-separated list, it is common to split the string into an array of elements.

After that, you might need to get the last element in the array.

In this post, we'll learn how to split a string into an array and get the last element in the array in JavaScript.

Split a string into an array

The easiest way to split a string into an array is to use the split() method.

This method takes a string as an argument and returns an array of elements.

First, let's define the string we want to split.

JAVASCRIPT
const string = "a,b,c,d,e";

Now let's split this by the comma character.

JAVASCRIPT
const string = "a,b,c,d,e";

const array = string.split(",");

As mentioned before, the split() method returns an array of elements.

JAVASCRIPT
const string = "a,b,c,d,e";

const array = string.split(",");

console.log(array);

// ["a", "b", "c", "d", "e"]

Get the last element in the array

Now that we have an array of elements, we can get the last element in the array.

The easiest way to get the last element in the array is to use the pop() method.

Let's use the pop() method to get the last element in the array.

JAVASCRIPT
const string = "a,b,c,d,e";

const array = string.split(",");

const lastElement = array.pop();

console.log(lastElement);

// e

Conclusion

In this post, we learned how to split a string into an array and get the last element in the array in JavaScript.

Simply use the split() method to split a string into an array and then use the pop() method to get the last element in the array.
