Checking if one array is contained in another inside an object

I'm struggling hard to try and get a (what i though would be simple) filter to work.

I have an array of objects:

data: 
  {
    0: {key: 'abc', name: ['bob', 'john', 'steve']},
    1: {key: 'def', name: ['bob']}
   }

I'm trying to an array to filter the object array:

filter: ['bob', 'john']

by using:

data.filter(v => v.name.includes(filter))

in the above, I would expect data[0] to be returned, and if I changed the filter to filter: ['bob'] then data[0,1] would be returned.

Unfortunately, nothing gets returned - and I can't quite seem to figure it out - it's probably simple, but any insight would be appreciated!

Assuming an array as data, you could filter by getting the name array and check each filter item against this array.

var data = [{ key: 'abc', name: ['bob', 'john', 'steve'] }, { key: 'def', name: ['bob'] }],
    filter = ['bob', 'john'],
    result = data.filter(({ name }) => filter.every(f => name.includes(f)));

console.log(result);
