Need to reload page after get 10 score poiint

I am making a simple game in JavaScript and I want to reload page after reach 10 points but in my case it's reloading infinitely. I am kinda new in JavaScript so I don't know how to fix this problem.

let click=0;
let gameScore=0;

function count(){
            click++;
            gameScore++;
        document.getElementById("mybutton").innerHTML = click;
        document.getElementById('score').innerHTML ="Score: " + gameScore;
}

            var div1=document.querySelector('div2');
            var div2 = div1.children[0];

        var d1=div1.getBoundingClientRect();
        var d2=div2.getBoundingClientRect();

                setInterval((d=[Math.floor(Math.random()*(d1.width-d2.width)),Math.floor(Math.random()*(d1.height-d2.height))])=>{
                        div2.style.transform = `translate(${d[0]}px, ${d[1]}px)`;
                            },1000);

                          if (gameScore => 10){ alert("YOU WON!");
                            document.location.reload()};
                            clearInterval(interval);
