# --description--
|
||
|
|
|
||
|
|
Create an empty `pick` function with a parameter named `guess`.
|
||
|
|
|
||
|
|
# --hints--
|
||
|
|
|
||
|
|
You should use the `function` keyword to declare `pick`.
|
||
|
|
|
||
|
|
```js
|
||
|
|
assert.match(code, /function\s+pick\s*/);
|
||
|
|
```
|
||
|
|
|
||
|
|
`pick` should take a parameter named `guess`.
|
||
|
|
|
||
|
|
```js
|
||
|
|
assert.match(pick.toString(), /pick\s*\(\s*guess\s*\)/);
|
||
|
|
```
|
||
|
