Array Grouping In Javascript Array Groupby Our groupby function is a curried function that makes use of partial application to help keep this function re usable. the groupby function takes a key (eg: 'year') as its only argument, and returns another function group, which in turn takes the array of objects that we'd like to sort. Here is a real group by for array of objects by some field (s) with 1) calculated key name and 2) complete solution for cascading of grouping by providing the list of the desired keys and converting its unique values to root keys like sql group by does.
