Write a solution to cleanup arrays. This can exist entirely in the squeakyClean function or contain multiple helper functions.

Your squeakyClean function should accept an input array of values and return a new array with all empty strings, 0, null and undefined removed.

Example:

var originalArray = ['click1','click2',null,'','','submitForm'];

the solution you write should return this:

var cleanedArray = ['click1', 'click2','submitForm']
