Nested loops & 2-dimensional arrays

Uses nested loops to print data from a 2-dimensional array.

Sample array:

var a = [[4, 2, 0], [8, 11, 9], [7, 0, 7], [7, 4, 28], [3, 10, 26]];

Output:

"row 0" "4" "2" "0" "row 1" “8” “11” “9” … etc

nestedloop2dArray.js

var a2dArray = [
	[4, 2, 0],
	[8, 11, 9],
	[7, 0, 7],
	[7, 4, 28],
	[3, 10, 26]
];

for(i=0; i<a2dArray.length; i++){
	var row2dArray = a2dArray[i];
	alert("row " + i);
	for(j=0; j<row2dArray.length; j++){
		alert(row2dArray[j]);
	}
}
