Tell us what’s happening:
I guess I don’t understand this if arr[3] [[10,11, 12] then wouldn’t arr[2][0] equal the 789?
Your code so far
// Setup
var myArray = [[1,2,3], [4,5,6], [7,8,9], [[10,11,12], 13, 14]];
// Only change code below this line.
var myData =[[1,2,3], [4,5,6], [7,8,9], [[10,11,12], 13, 14]];
arr[1];
