###  Problem Explanation:
Remove all falsy values from an array.
#### Relevant Links
* Falsy Values
##  Hint: 1
Falsy is something which evaluates to FALSE. There are only six falsy values in JavaScript: undefined, null, NaN, 0, "" (empty string), and false of course.

##  Hint: 2
We need to make sure we have all the falsy values to compare, we can know it, maybe with a function with all the falsy values...
> _try to solve the problem now_
##  Hint: 3
Then we need to add a `filter()` with the falsy values function...

## Spoiler Alert!
**Solution ahead!**
##  Advanced Code Solution:
function bouncer(arr) {
return arr.filter(Boolean);
}
 Run Code
### Code Explanation:
The `Array.prototype.filter` method expects a function that returns a `Boolean` value which takes a single argument and returns `true` for truthy value or `false` for falsy value. Hence we pass the built-in `Boolean` function.
