# --description--
Bracket notation is a way to get a character at a specific index within a string.
Most modern programming languages, like JavaScript, don't start counting at 1 like humans do. They start at 0. This is referred to as Zero-based indexing.
For example, the character at index 0 in the word `Charles` is `C`. So if `const firstName = "Charles"`, you can get the value of the first letter of the string by using `firstName[0]`.
Example:
```js
const firstName = "Charles";
const firstLetter = firstName[0];
```
`firstLetter` would have a value of the string `C`.
# --instructions--
Use bracket notation to find the first character in the `lastName` variable and assign it to `firstLetterOfLastName`.
**Hint:** Try looking at the example above if you get stuck.
# --hints--
The `firstLetterOfLastName` variable should have the value of `L`.
```js
assert(firstLetterOfLastName === 'L');
```
You should use bracket notation.
```js
assert(code.match(/firstLetterOfLastName\s*=\s*lastName\s*\[\s*\d\s*\]/));
```
# --seed--
## --after-user-code--
```js
(function(v){return v;})(firstLetterOfLastName);
```
## --seed-contents--
```js
// Setup
let firstLetterOfLastName = "";
const lastName = "Lovelace";
// Only change code below this line
firstLetterOfLastName = lastName; // Change this line
```
# --solutions--
```js
let firstLetterOfLastName = "";
const lastName = "Lovelace";
// Only change code below this line
firstLetterOfLastName = lastName[0];
```
