Not sure what's the problem? Access Multi-Dimensional Arrays With Indexes

JavaScript
1

Tell us what’s happening:
What am I doing wrong? It tells me that"myData should be equal to 8. You should be using bracket notation to read the correct value from myArray".

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 = myArray[3][1];

close – are you SURE about the index of the first array? Remember, arrays are zero based.
