| # --description--
 | |
| 
 | |
| In a `switch` statement you may not be able to specify all possible values as `case` statements. Instead, you can add the `default` statement which will be executed if no matching `case` statements are found. Think of it like the final `else` statement in an `if/else` chain.
 | |
| 
 | |
| A `default` statement should be the last case.
 | |
| 
 | |
| ```js
 | |
| switch (num) {
 | |
|   case value1:
 | |
|     statement1;
 | |
|     break;
 | |
|   case value2:
 | |
|     statement2;
 | |
|     break;
 | |
| ...
 | |
|   default:
 | |
|     defaultStatement;
 | |
|     break;
 | |
| }
 | |
| ```
 | |
| 
 | |
| # --instructions--
 | |
| 
 | |
| Write a switch statement to set `answer` for the following conditions:  
 | |
| `a` - `apple`  
 | |
| `b` - `bird`  
 | |
| `c` - `cat`  
 | |
| `default` - `stuff`
 | |
| 
 | |
| # --hints--
 | |
| 
 | |
| `switchOfStuff("a")` should return the string `apple`
 | |
| 
 | |
| ```js
 | |
| assert(switchOfStuff('a') === 'apple');
 | |
| ```
 | |
| 
 | |
| `switchOfStuff("b")` should return the string `bird`
 | |
| 
 | |
| ```js
 | |
| assert(switchOfStuff('b') === 'bird');
 | |
| ```
 | |
| 
 | |
| `switchOfStuff("c")` should return the string `cat`
 | |
| 
 | |
| ```js
 | |
| assert(switchOfStuff('c') === 'cat');
 | |
| ```
 | |
| 
 | |
| `switchOfStuff("d")` should return the string `stuff`
 | |
| 
 | |
| ```js
 | |
| assert(switchOfStuff('d') === 'stuff');
 | |
| ```
 | |
| 
 | |
| `switchOfStuff(4)` should return the string `stuff`
 | |
| 
 | |
| ```js
 | |
| assert(switchOfStuff(4) === 'stuff');
 | |
| ```
 | |
| 
 | |
| You should not use any `if` or `else` statements
 | |
| 
 | |
| ```js
 | |
| assert(!/else/g.test(code) || !/if/g.test(code));
 | |
| ```
 | |
| 
 | |
| You should use a `default` statement
 | |
| 
 | |
| ```js
 | |
| assert(switchOfStuff('string-to-trigger-default-case') === 'stuff');
 | |
| ```
 | |
| 
 | |
| You should have at least 3 `break` statements
 | |
| 
 | |
| ```js
 | |
| assert(code.match(/break/g).length > 2);
 | |
| ```
 | |

 | |
| ```js
 | |
| function switchOfStuff(val) {
 | |
|   var answer = "";
 | |
|   // Only change code below this line
 | |
|

| 
 | |
| 
 | |
|   // Only change code above this line
 | |
|   return answer;
 | |
| }
 | |
| 
 | |
| switchOfStuff(1);
 | |
| ```
 | |
| 
 | |
| # --solutions--
 | |
| 
 | |
| ```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;
 | |
| }
 | |
| ```
