How to get last character of a string in JavaScript

In this tutorial, we will learn two different ways to get the last character of a string in JavaScript.

In JavaScript, strings are the sequence of characters, where the index of the first character is 0, the second character is 1, third character is 3 and last character index is string.length-1 etc.

1. Using charAt() method

To get the last character of a string in JavaScript, we can use the built-in charAt() method by passing string.length-1 as an argument to it.

The string.length-1 returns the index of a last character.

Here is an example:

const str = "hello";

const lastCharacter = str.charAt(str.length-1);
console.log(lastCharacter); // "o"

2. Using slice() method

If we pass -1 as an argument to the slice() method we can get the last character of a string.

const string = "hello";

const lastCharacter = string.slice(-1);
console.log(lastCharacter); // "o"

Note: Negative index -1 is same as string.length-1.
