--- id: bd7123c9c451eddfaeb5bdef title: Use Bracket Notation to Find the Last Character in a String challengeType: 1 --- ## Description <section id='description'> In order to get the last letter of a string, you can subtract one from the string's length. For example, if <code>var firstName = "Charles"</code>, you can get the value of the last letter of the string by using <code>firstName[firstName.length - 1]</code>. </section> ## Instructions <section id='instructions'> Use <dfn>bracket notation</dfn> to find the last character in the <code>lastName</code> variable. <strong>Hint</strong><br>Try looking at the <code>lastLetterOfFirstName</code> variable declaration if you get stuck. </section> ## Tests <section id='tests'> ```yml 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.'); ``` </section> ## Challenge Seed <section id='challengeSeed'> <div id='js-seed'> ```js // Example var firstName = "Ada"; var lastLetterOfFirstName = firstName[firstName.length - 1]; // Setup var lastName = "Lovelace"; // Only change code below this line. var lastLetterOfLastName = lastName; ``` </div> ### After Test <div id='js-teardown'> ```js (function(v){return v;})(lastLetterOfLastName); ``` </div> </section> ## Solution <section id='solution'> ```js var firstName = "Ada"; var lastLetterOfFirstName = firstName[firstName.length - 1]; var lastName = "Lovelace"; var lastLetterOfLastName = lastName[lastName.length - 1]; ``` </section>
