Lodash filter by object of object

How to filter items by type?

const items = {
        'someHash0': {
          type: 'foo',
          name: 'a'
        },
        'someHash1': {
          type: 'foo',
          name: 'b'
        },
        'someHash2': {
          type: 'foo',
          name: 'c'
        },
        'someHash3': {
          type: 'baz',
          name: 'd'
        },
      };

I want to filter by type=foo and get that result:

const items = {
        'someHash0': {
          type: 'foo',
          name: 'a'
        },
        'someHash1': {
          type: 'foo',
          name: 'b'
        },
        'someHash2': {
          type: 'foo',
          name: 'c'
        }
      };

I tryied with

 return _.mapValues(pairs, function (item) {
     return (item.type === 'foo') ?? item
})

but it returns true/false instead of the whole object

>Solution :

map in general is for editing iterated inputs, so it’s not what you need.

You can do like this:

let result = _.filter(items, x => x.type === 'foo')

If you need to keep the same keys you could do it like this :

let result = _.pickBy(items, x => x.type === 'foo')
