Javascript/VUE2: How to check value for multiple matches,

I am trying to make a full house combination in the game of Yahtzee. (3 of the same dice and 2 of the same)

I have a function that count occurences and will output in here after the random dice generator function:

   countDice:      {1: 0, 2: 0, 3: 0, 4: 0, 5: 0, 6: 0},

I want to check if the value has a 3 and a 2. And then return 25. I tried to access it with Object.values and some other ways with loops and etc. I tried it with filter but that seems to only work on an object in array and then the rest of my code messes up.

I have tried this as last :

 function has(obj, value) {
                    for(var value in obj) {
                        if(this.countDice.value === 3 this.countDice.value === 2 ) {
                        return 25;
                        }
                    }

Nothing happens. I have been messing around with every, and some. I am stuck on a simple thing here it seems :s can anyone help me?
