Find Mistake

Question

I have been trying to find the mistake for an hour but couldn't. Can you please help me find the mistake in the follwing JavaScript code.

JavaScript Code:
documentvar matrix = [
[1, 2, 3],
[4, 5, 6],
[7, 8, 9]
];
for (var i = 0; i < matrix.length; i++) {
for (var j = 0; j <= matrix[i].length; j++) {
console.log(matrix[i][j]);
}
}

Expected Behavior:

Initialize a 2D array matrix with the values [[1, 2, 3], [4, 5, 6], [7, 8, 9]].

Use a nested for loop to iterate over each element of the 2D array.

Log each element of the 2D array to the console.

Answer 1

interesting.... documentvar exists?
