 * Use Array.prototype.push() to add elements for which fn returns true to the

 * Given an array of valid property identifiers and an array of values,

 * Removes elements from an array for which the given function returns false.
 * Use Array.prototype.filter() to find array elements that return truthy 
 * values and Array.prototype.reduce() to remove elements using 
 * Array.prototype.splice(). The func is invoked with three 
 * arguments (value, index, array).
