Question

I have a multidimensional array of bools, with each element set to true:

var boolarray= $.extend(true, [], board);

board is a 3×3 multidimensional array of strings. boolarray is simply a deep copy of this.

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

This gives me:

boolarray = [true,true,true,true,true,true,true,true,true]

I want to check if all elements are true and return if this is the case. However my method below does not work.

if (boolarray == true)
{
console.log("all elements in boolarray are true, return true ")
return true;
}
else 
{
console.log("not all elements in boolarray are true, return false")
return false;
}

Any ideas of how I should check if boolarray is all true?

You would need to loop through the array again to check all the values; in a very similar way to how you assigned them:

for (var i=0; i < boolarray.length; i++) {
    for (var j=0; j < boolarray[i].length; j++) {
        if (boolarray[i][j] == false) {
            return false;
        }
    };
}; 

return true;
