Check if all values of array are equal to number

I want to see if there is a better way to check if all values of array are equal to number. I have it working with a foreach but wanted to see if I can do this anyway else?

let valid = true;
$.each(data.resultStatus, function (index, resultStatus) {
    if (resultStatus.ResultCode == "2") {
        valid = false;
   }
});
