    I want to recieve feedback about my solution in Javascript. How can I do it better?:

    function sockMerchant(n, ar) {
    ar.sort((a, b)=> a - b)
    let pairs=0;
    for(let i=0;i<ar.length;i++){
        if(ar[i]===ar[i+1]){
            pairs++;
            i++;
        }
    }
    return pairs;
}
