# --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 `0`, so the first character is actually the zeroth character.
Example:
```js
var firstName = "Ada";
var secondLetterOfFirstName = firstName[1];
```
`secondLetterOfFirstName` would have a value of the string `d`.
# --instructions--
Let's try to set `thirdLetterOfLastName` to equal the third letter of the `lastName` variable using bracket notation.
**Hint:** Try looking at the example above if you get stuck.
# --hints--
The `thirdLetterOfLastName` variable should have the value of `v`.
```js
assert(thirdLetterOfLastName === 'v');
```
You should use bracket notation.
```js
assert(code.match(/thirdLetterOfLastName\s*?=\s*?lastName\[.*?\]/));
```
# --seed--
## --after-user-code--
```js
(function(v){return v;})(thirdLetterOfLastName);
```
## --seed-contents--
```js
// Setup
var lastName = "Lovelace";
// Only change code below this line
var thirdLetterOfLastName = lastName; // Change this line
```
# --solutions--
```js
var lastName = "Lovelace";
var thirdLetterOfLastName = lastName[2];
```
