## Extremes |

|
||||
find the bigest and smallest number of the list |
||||
### Instructions |
||||
|
||||
Create a function `extreme` that given an array of number find the bigest and |
||||
smallest number of the array |
||||
|
||||
**Examples:** |
||||
|
||||
```js |
||||
extreme([-1, 0, 10, 5]) // -> { bigest: 10, smallest: -1 } |
||||
extreme([22, 7, 32, 99, 54]) // -> { bigest: 99, smallest: 7 } |
||||
``` |

### Looping with the `while` keyword |
||||
|
||||
Loops are one of the last missing basic blocks of programing left to learn, |
||||
let's see it in action: |
||||
|
||||
```js |
||||
while (count < 30) { |
||||
// Code to be repeated here |
||||
} |
||||
``` |
||||
|
||||
As you can see, it is exactly like an `if`, we have a scope `{}` and a |
||||
`(condition)` just a new keyword. |
||||
|
||||
Unlike the `if` however, the code inside the scope will be executed as long as |
||||
the condition is `true` |
||||
|
||||
It is easy to get stuck in an never ending loop as if your condition is never |
||||
`false` you will always be stuck in a loop |
||||
|
||||
As such it is common to have some kind of iteration inside our looping code: |
||||
|
||||
```js |
||||
while (count < 30) { |
||||
count = count + 1 |
||||
} |
||||
``` |
||||
|
||||
Now everytime our code is executed, the value of `count` will be `incremented` |
||||
by `1`, until it reach `30` and stop. |
||||
|
||||
> If your code is stuck in an infinite loop, you can do a Ctrl+C shortcut in the |
||||
> terminal to interrupt the code |
||||
|
||||
### Instructions |
||||
|
||||
Write a function `goTo11` that takes a `start` number argument and call |
||||
`console.log` on each numbers from the `start` (included) up to and including |
||||
`11`. |
||||
|
||||
If the `start` is higher than `11` your function must do nothing. |
