var myArray = [[1, 2, 3], [4, 5, 6], [7, 8, 9]];

In this specific exercise, you are typically asked to modify an existing 2D array. This often involves: through every element using nested loops. Evaluating the current value at a specific position. Codehs 8.1.5 Manipulating 2d Arrays

If you're stuck on a specific part of the code, I can help you debug it! Just let me know: What are you seeing (if any)? var myArray = [[1, 2, 3], [4, 5,

// Double every element for (int row = 0; row < matrix.length; row++) for (int col = 0; col < matrix[row].length; col++) matrix[row][col] *= 2; If you're stuck on a specific part of

To manipulate a 2D array, you cannot use a single for loop. You need : one loop to iterate through the rows (outer loop) and one loop to iterate through the columns (inner loop). Standard Structure
