--description--

<dfn>Bracket notation</dfn> 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 <dfn>Zero-based</dfn> 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:

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.

assert(firstLetterOfLastName === 'L');

You should use bracket notation.

assert(__helpers.removeJSComments(code).match(/firstLetterOfLastName\s*=\s*lastName\s*\[\s*\d\s*\]/));

--seed--

--seed-contents--

// Setup
let firstLetterOfLastName = "";
const lastName = "Lovelace";

// Only change code below this line
firstLetterOfLastName = lastName; // Change this line

--solutions--

let firstLetterOfLastName = "";
const lastName = "Lovelace";

// Only change code below this line
firstLetterOfLastName = lastName[0];
