## 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"
```

## Instructions
<section id='instructions'>
Use <dfn>bracket notation</dfn> to find the last character in the <code>lastName</code> variable.
<strong>Hint: </strong> Try looking at the example above if you get stuck.

## Tests

  - text: <code>lastLetterOfLastName</code> should be "e".
    testString: assert(lastLetterOfLastName === "e");
  - text: You should use <code>.length</code> to get the last letter.
    testString: assert(code.match(/\.length/g).length > 0);

```
