    function getCount(objects) { return objects.filter(obj => obj.x === obj.y).length; }

    In JS

    function getCount(objects) {
    let count =0
    for(const obj of objects){
        if(obj.x===obj.y){
            count++;
        }
    }
    return count;
}

    function getCount(objects) { let count = 0 const map = objects.map((item) => { if(item.x == item.y){ count +=1 } }) return count }

    function getCount(objects) {
  let count = 0;

  for (let i = 0; i < objects.length; i++) {
    const arr = Object.values(objects[i]);
    if (arr[0] === arr[1]) {
      count++;
    }
  }
  console.log("total", count);
  return count;
}

    And just because we can, here is a version using reducer:

    function getCount(objects) {
    return objects.reduce((prev, o) => {
        return prev + (o.x == o.y);
    }, 0);
}
