I fount this problem on HackerRank, 10 days of JavaScript
1. An array of objects is given.
2. Each object in the array has two integer properties: x and y
3. Count the total number of objects obj satisfying obj.x == obj.y.
My solution:
function getCount(objects) {
let arrayItems = objects.filter((item) => {
return item.x == item.y;
});
return arrayItems.length;
}
