Script Preparation code:

function createObjectsArray(n) {
	let arr = [];
  	const salt=(Math.random() + '').slice(2,3);
  	while(n > 0) {
    	arr.push({
        	id: n+salt,
          name: 'name' + n + salt
        })
      n--;
    }
  return arr;
}
//var listOfObjects_1 = [{id: 1, name: '1'}, {id: 2, name: '2'}, {id: 5, name: '5'}]
var listOfObjects_1 = createObjectsArray(1000)
//var listOfObjects_2 = [{id: 1, name: '1'}, {id: 2, name: '2'}, {id: 5, name: '4'}]
var listOfObjects_2 = createObjectsArray(1000)

Tests:

array filtering with some
listOfObjects_1.filter(selectedItem => listOfObjects_2.some(item => item.id === selectedItem.id) )
array filtering with includes
var ids_1 = listOfObjects_1.map(o => o.id) listOfObjects_2.filter(o => ids_1.includes(o.id))
