## Description
< section id = 'description' >
In order to get the last letter of a string, you can subtract one from the string's length.
For example, if < code > var firstName = "Charles"< / code > , you can get the value of the last letter of the string by using < code > firstName[firstName.length - 1]< / code > .

Example:
```js
var firstName = "Charles";
var lastLetter = firstName[firstName.length - 1]; // lastLetter is "s"
```
