JavaScript filter array by data from another

Question

I have an array object:

[
    { id:1, name: 'Pedro'},
    { id:2, name: 'Miko'},
    { id:3, name: 'Bear'},
    { id:4, name: 'Teddy'},
    { id:5, name: 'Mouse'}
]

And I have an array with ids [1, 3, 5],

How can I filter the array object to leave records only with id's from the second one?

If Array.includes() is supported, you can use it with Array.filter() to get the items:

const array = [
  { id: 1, name: 'Pedro'},
  { id: 2, name: 'Miko'},
  { id: 3, name: 'Bear'},
  { id: 4, name: 'Teddy'},
  { id: 5, name: 'Mouse'}
];

const filterArray = [1,3,5];

const result = array.filter(({ id }) => filterArray.includes(id));

console.log(result);

If includes is not supported, you can use Array.indexOf() instead:

var array = [
  { id: 1, name: 'Pedro'},
  { id: 2, name: 'Miko'},
  { id: 3, name: 'Bear'},
  { id: 4, name: 'Teddy'},
  { id: 5, name: 'Mouse'}
];

var filterArray = [1,3,5];

var result = array.filter(function(item) {
    return filterArray.indexOf(item.id) !== -1;
});

console.log(result);
