Master the Grid: A Guide to CodeHS 8.1.5 Manipulating 2D Arrays
console.log(array); // output: [[1, 2, 3, 10], [4, 5, 6, 10], [7, 8, 9, 10]] return result;You cannot effectively manipulate a 2D array without understanding nested loops.
: Standard practice is to iterate through the row first, then the column. This is how Java stores 2D arrays in memory. 4. Pro-Tip: Watch Out for IndexOutOfBounds The most common headache in this lesson is the IndexOutOfBoundsException
