# --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);
```
# --seed--
## --seed-contents--
```js
function switchOfStuff(val) {
let answer = "";
// Only change code below this line
// Only change code above this line
return answer;
}
switchOfStuff(1);
```
# --solutions--
```js
function switchOfStuff(val) {
let answer = "";
switch(val) {
case "a":
answer = "apple";
break;
case "b":
answer = "bird";
break;
case "c":
answer = "cat";
break;
default:
answer = "stuff";
}
return answer;
}
```
