and have array 

var elementarray = ["0-7-3","2-10-0","2-11-0","2-12-1"]

is there shortcut update array of arrays according elements in second array update 7th array of 0th array's 3rd column true. appreciated.

you can split out index , use on large array.

var elementarray = ["0-7-3","2-10-0","2-11-0","2-12-1"]; for(var = 0; < elementarray.length; i++){   var idx = elementarray[i].split('-');   arrayofarrays[idx[0]][idx[1]][idx[2]] = true; }
