filter an array based on another array inside the main one

Question

I have an array of data similar to this structure:

const array = [
  {
    name: 'name',
    tags: [
      {
        name: 'xxxx',
        url: '/this',
      },
    ],
  },
  {
    name: 'name',
    tags: [
      {
        name: 'xxxxxxx',
        url: '/that',
      },
    ],
  },
];

I would like to return for example, the objects that contain only the url:'this'.

i tried to map the outer array first, and then using filter in the nested tag array, but without any luck. Any suggestions? thanks

do you want only the inner objects or only the outer or the outer with only the matching inner object? what have you tried? — Nina Scholz, Dec 14 '22 at 12:16

This works even when tags has multiple objects in its array

const arr = [{
  name: 'name',
  tags: [{
    name: 'xxxx',
    url: '/this'
  }]
}, {
  name: 'name',
  tags: [{
    name: 'xxxxxxx',
    url: '/that'
  }]
}]


console.log(arr.filter((item) => item.tags.some((tag) => tag.url === "/this")))
