Creates a flattened array of values by running each element in collection thru iteratee and flattening the mapped results.The iteratee is invoked with three arguments: (value, index|key, collection). The lodash _.forEach method is one of the many methods in lodash that is a collection method meaning it will work well with just about any object that is a collection of key value pairs in general, not just keys that are numbered and an instance of the javaScript array constructor. So it could easily being turned into this when I want to change value without knowing the location in the object.
