Implement a Falsy Remover
In this lab you will create a function that removes all falsy values from an array.
Falsy values in JavaScript are `false`, `null`, `0`, `""`, `undefined`, and `NaN`.
**Objective**: Fulfill the user stories below and get all the tests to pass to complete the lab.
**User Stories:**
1. You should have a `bouncer` function that takes an array as argument.
1. The `bouncer` function should return a new array that contains the same elements as the array passed in as argument with the falsy elements removed.
1. The `bouncer` function should not change the array passed in as an argument.
Hint: Try converting each value to a Boolean.
