Javascript compare 3 values

Question

I have 3 values that I want to compare f, g and h. I have some code to check that they all equal each other and that none of them are null. I\'ve had a look online but could

Answer 1

Write a simple function:

var checkAllArguments = function() {
    var len = arguments.length;
    var obj;

    if(len == 0) {
        return true;
    } else {
        if(arguments[0] == null) {
            return false;
        } else {
            obj = arguments[0];
        }
    }

    for(var i=1; i<len; i++) {
        if(arguments[i] == null) {
            return false;
        }

        if(obj == arguments[i]) {
            continue;
        } else {
            return false;
        }
    }

    return true;
}

Now, to check multiple arguments, all you have to do is:

if(checkAllArguments(g, h, f)) {
   // Do something
}
