How to dedupe pair of random numbers in JavaScript : I have a function that generates random numbers given a range I want to make sure I don't re-generate the same pair of numbers.

       function generateRandomInt(max) {
              return Math.floor(Math.random() * Math.floor(max));
        }
        
        let randomInt1 = generateRandomInt(10) + 1;
        let randomInt2 = generateRandomInt(10) + 1;
    
        let numberStore = randomInt1 + "" + randomInt2; 
    
    console.log(randomInt1);
    console.log(randomInt2);
    console.log(parseInt(numberStore));

`numberStore` contains the result of `randomInt1` and `randomInt2` I want to avoid having a pair of numbers that were already generated.
