Javascript doesn't support two-dimensional arrays, but on the other
hand, you don't need to declare the number of elements in an array,
either.

var myArray=new Array();
myArray[237]=new Array();
myArray[237][12]="Hello, world!";

oh i see, how about this one ,another question. I have 3
two-dimensional array, i want to merge these 3 arrays so that it will
become only 1 two-dimensional array. Is it possible? If it is, how will
i dot that?

Have you tried something like:

j=target_array. length;
for (var i=0; i<source_array. length; i++) {
target_array[j] = source_array[i];
j++;
}

?

var prem=
[["Arsenal",12,3, 2],["Chelsea",12,5, 0],["Fulham",6, 6,6],["Tottenham",4,4 ,8]];

prem[1][0] =="Chelsea" //true
