arr = [1, 2, 3, 4, 1, 2, 3, 3, 3];

const map = new Map();

arr.forEach((element) => {
if (map.has(element)) {
map.set(element, map.get(element) + 1);
} else {
map.set(element, 1);
}
});

const objFormat = Object.fromEntries(map);
console.log(objFormat);

// Try this

The last question, "occurrence of array elements," does not like a standard approach.
