bd7123c9c451eddfaeb5bdef Use Bracket Notation to Find the Last Character in a String 1 https://scrimba.com/c/cBZQGcv 18342 use-bracket-notation-to-find-the-last-character-in-a-string

--description--

In order to get the last letter of a string, you can subtract one from the string's length.

For example, if const firstName = "Ada", you can get the value of the last letter of the string by using firstName[firstName.length - 1].

Example:

const firstName = "Ada";
const lastLetter = firstName[firstName.length - 1];

lastLetter would have a value of the string a.

--instructions--

Use bracket notation to find the last character in the lastName variable.

Hint: Try looking at the example above if you get stuck.

--hints--

lastLetterOfLastName should be the letter e.

assert(lastLetterOfLastName === 'e');

You should use .length to get the last letter.

assert(__helpers.removeJSComments(code).match(/\.length/g).length > 0);

--seed--

--after-user-code--

(function(v){return v;})(lastLetterOfLastName);

--seed-contents--

// Setup
const lastName = "Lovelace";

// Only change code below this line
const lastLetterOfLastName = lastName; // Change this line

--solutions--

const lastName = "Lovelace";
const lastLetterOfLastName = lastName[lastName.length - 1];
