## Description
Eliminar todos los valores falsos de una matriz. Los valores de false en JavaScript son false , null , 0 , "" , undefined y NaN . Sugerencia: intente convertir cada valor a un booleano. Recuerda usar Read-Search-Ask si te atascas. Escribe tu propio código.
## Instructions
## Tests
```yml
tests:
- text: 'bouncer([7, "ate", "", false, 9]) debe devolver [7, "ate", 9] .'
testString: 'assert.deepEqual(bouncer([7, "ate", "", false, 9]), [7, "ate", 9], "bouncer([7, "ate", "", false, 9]) should return [7, "ate", 9].");'
- text: 'bouncer(["a", "b", "c"]) debe devolver ["a", "b", "c"] .'
testString: 'assert.deepEqual(bouncer(["a", "b", "c"]), ["a", "b", "c"], "bouncer(["a", "b", "c"]) should return ["a", "b", "c"].");'
- text: 'bouncer([false, null, 0, NaN, undefined, ""]) debe devolver [] .'
testString: 'assert.deepEqual(bouncer([false, null, 0, NaN, undefined, ""]), [], "bouncer([false, null, 0, NaN, undefined, ""]) should return [].");'
- text: 'bouncer([1, null, NaN, 2, undefined]) debe devolver [1, 2] .'
testString: 'assert.deepEqual(bouncer([1, null, NaN, 2, undefined]), [1, 2], "bouncer([1, null, NaN, 2, undefined]) should return [1, 2].");'
```
