Description

In order to get the last letter of a string, you can subtract one from the string's length. For example, if var firstName = "Charles", you can get the value of the last letter of the string by using firstName[firstName.length - 1].

Instructions

Use bracket notation to find the last character in the lastName variable. Hint
Try looking at the lastLetterOfFirstName variable declaration if you get stuck.

Tests

- text: <code>lastLetterOfLastName</code> should be "e".
  testString: 'assert(lastLetterOfLastName === "e", "<code>lastLetterOfLastName</code> should be "e".");'
- text: You have to use <code>.length</code> to get the last letter.
  testString: 'assert(code.match(/\.length/g).length === 2, "You have to use <code>.length</code> to get the last letter.");'

Challenge Seed

// Example
var firstName = "Ada";
var lastLetterOfFirstName = firstName[firstName.length - 1];

// Setup
var lastName = "Lovelace";

// Only change code below this line.
var lastLetterOfLastName = lastName;

After Test

console.info('after the test');

Solution

var firstName = "Ada";
var lastLetterOfFirstName = firstName[firstName.length - 1];

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