I am getting started on React Virtualized and while doing a table with sortable columns, I noticed that the documentation and examples are all including a "sortBy" function. See documentation here
But I can't see that sortBy function being imported anywhere.
Is it expected that you make your own sortBy function or is React Virtualized coming with it and if so, how do I "import/activate" it?
For now I made it work with my own function but I am curious to know what is this "sortBy" function that is being referred to in the documentation.
