## Description
<section id='description'>
You can also use <dfn>bracket notation</dfn> to get the character at other positions within a string.
Remember that computers start counting at <code>0</code>, so the first character is actually the zeroth character.

Example:

```js
var firstName = "Ada";
var secondLetterOfFirstName = firstName[1]; // secondLetterOfFirstName is "d"
```

</section>

## Instructions
<section id='instructions'>
Let's try to set <code>thirdLetterOfLastName</code> to equal the third letter of the <code>lastName</code> variable using bracket notation.
<strong>Hint: </strong> Try looking at the example above if you get stuck.

## Tests
<section id='tests'>

```yml
tests:
  - text: The <code>thirdLetterOfLastName</code> variable should have the value of <code>v</code>.
    testString: assert(thirdLetterOfLastName === 'v');
  - text: You should use bracket notation.
    testString: assert(code.match(/thirdLetterOfLastName\s*?=\s*?lastName\[.*?\]/));

```
