## level up
You know now, in your function declarations, how to use arguments and returns.
Let's try to now use the `if` statements in a new function called `happy`. Here
is an example:
```js
let happy = (mood) => {
if (mood === 'happy') {
return true
}
return false
}
let result1 = happy('happy')
let result2 = happy('sad')
console.log(result1) //true
console.log(result2) //false
```
Here we used the `if` statement, and two `return` keywords to alternate between
the result `true` or `false` depending whether the argument `mood` is equal to
the string `happy` or not. The possibilities are becoming limitless...
### Instructions
As Rick's robot, you are continuing your training to add yourself new ... skills
(I could have said funtions). You want now to become a robot bartender.
Define the function `shaker` which will take as arguments:
- `quantity`, which will be variable of type `Number`
- `fruit`, which will be a `String`
- `alcohol`, which will be a `Boolean`
`shaker` must return a `String`. Look at the examples below to understand how
`shaker` must mix its ingredients:
```js
console.log(shaker(1, 'strawberry', true))
//'1 strawberry cocktail'
console.log(shaker(2, 'chocolate', false))
//'2 chocolate milkshakes'
console.log(shaker(2, 'strawberry', true))
//'2 strawberry cocktails'
console.log(shaker(1, 'chocolate', false))
//'1 chocolate milkshake'
```
Ps: watch out for your plurals!
