--- id: 56533eb9ac21ba0edf2244de title: Adding a Default Option in Switch Statements challengeType: 1 guideUrl: 'https://www.freecodecamp.org/guide/certificates/adding-a-default-option-in-switch-statements' --- ## Description <section id='description'> In a <code>switch</code> statement you may not be able to specify all possible values as <code>case</code> statements. Instead, you can add the <code>default</code> statement which will be executed if no matching <code>case</code> statements are found. Think of it like the final <code>else</code> statement in an <code>if/else</code> chain. A <code>default</code> statement should be the last case. <blockquote>switch (num) {<br> case value1:<br> statement1;<br> break;<br> case value2:<br> statement2;<br> break;<br>...<br> default:<br> defaultStatement;<br> break;<br>}</blockquote> </section> ## Instructions <section id='instructions'> Write a switch statement to set <code>answer</code> for the following conditions:<br><code>"a"</code> - "apple"<br><code>"b"</code> - "bird"<br><code>"c"</code> - "cat"<br><code>default</code> - "stuff" </section> ## Tests <section id='tests'> ```yml tests: - text: <code>switchOfStuff("a")</code> should have a value of "apple" testString: 'assert(switchOfStuff("a") === "apple", "<code>switchOfStuff("a")</code> should have a value of "apple"");' - text: <code>switchOfStuff("b")</code> should have a value of "bird" testString: 'assert(switchOfStuff("b") === "bird", "<code>switchOfStuff("b")</code> should have a value of "bird"");' - text: <code>switchOfStuff("c")</code> should have a value of "cat" testString: 'assert(switchOfStuff("c") === "cat", "<code>switchOfStuff("c")</code> should have a value of "cat"");' - text: <code>switchOfStuff("d")</code> should have a value of "stuff" testString: 'assert(switchOfStuff("d") === "stuff", "<code>switchOfStuff("d")</code> should have a value of "stuff"");' - text: <code>switchOfStuff(4)</code> should have a value of "stuff" testString: 'assert(switchOfStuff(4) === "stuff", "<code>switchOfStuff(4)</code> should have a value of "stuff"");' - text: You should not use any <code>if</code> or <code>else</code> statements testString: 'assert(!/else/g.test(code) || !/if/g.test(code), "You should not use any <code>if</code> or <code>else</code> statements");' - text: You should use a <code>default</code> statement testString: 'assert(switchOfStuff("string-to-trigger-default-case") === "stuff", "You should use a <code>default</code> statement");' - text: You should have at least 3 <code>break</code> statements testString: 'assert(code.match(/break/g).length > 2, "You should have at least 3 <code>break</code> statements");' ``` </section> ## Challenge Seed <section id='challengeSeed'> <div id='js-seed'> ```js function switchOfStuff(val) { var answer = ""; // Only change code below this line // Only change code above this line return answer; } // Change this value to test switchOfStuff(1); ``` </div> </section> ## Solution <section id='solution'> ```js function switchOfStuff(val) { var answer = ""; switch(val) { case "a": answer = "apple"; break; case "b": answer = "bird"; break; case "c": answer = "cat"; break; default: answer = "stuff"; } return answer; } ``` </section>
