How to print the following Multi-Dimensional array in JavaScript?

Question

I have the following array (the code is written in Java) :

String[][] a = new String[3][2];
a[0][0] = \"1\"; 
a[0][1] = \"2\"; 

a[1][0] = \"1\";  
a[1][1]          


        

Answer 1

var a = [];

a[0] = [];
a[0][0] = "1";
a[0][1] = "2";

a[1] = [];
a[1][0] = "1";
a[1][1] = "2";

a[2] = [];
a[2][0] = "1";
a[2][1] = "2";

for (i = 0; i < a[i].length; i++) {
    for (j = 0; j < a.length; j++) {
        document.write(a[j][i]);
    }
}
