You can tell how many dimensions an array has by how many individual indices you need to access the values. let's add some values to the above array and access one:
constarr=[[1],[2],[3]]constvalue=arr[0][0]// value is 1
Notice that we need two indices to access the values. An array of three dimensions would be nested such that you need three indices. For example:
constarr=[[[1],[2]],[[3],[4]],[[5],[6]]]constvalue=arr[0][0][0]// value is 1
Thank you Ryan!!! You teach me something new. i think here in this example: [[],[],[]] it's a 3d array?!

Thanks so much Ryan, it makes a lot of sense now.
