In this step we have this statement:
This is known as a multi-dimensional array, or an array that contains other arrays.
In my own research I’ve run into bunch of definitions like:
A multidimensional array or object is one that has one or more nested arrays or objects as property values .
And some other which are not exactly clear
Need some clarification:
Array of objects or array of sets - is it considered multidimensional or not?
