How do i filter an array inside of a array of objects value [duplicate]

Question

const data = [
  { name: "name1", option: "option1", category: [{ id: 1, value: "national" }] },
  { name: "name2", option: "option2", category: [{ id: 2, value: "international" }] },
  { name: "name3", option: "option3", category: [{ id: 3, value: "sports" }] },
  { name: "name4", option: "option4", category: [{ id: 4, value: "entertainment" }] },
];

I would like to filter of this array value of category // // console.log(data);

const result = data.filter(e => {
  return e.category.filter(b => b.value === 'national')
})

// I want output like bellow

{ name: "name1", option: "option1", category: [{ id: 1, value: "national" }] },

What's the final result you are looking for and what have you tried that is not working ? — Orelsanpls

data.filter(e => e.category.some(b => b.value === 'national'))…? Keeps all data items that have any 'national' value in category. — deceze

I modify the code for multiple arrays in category:

const data = [
  { name: "name1", option: "option1", category: [{ id: 1, value: "national" }, {id: 1, value: "mundial" }]},
  { name: "name2", option: "option2", category: [{ id: 2, value: "international" }] },
  { name: "name3", option: "option3", category: [{ id: 3, value: "sports" }] },
  { name: "name4", option: "option4", category: [{ id: 4, value: "entertainment" }] },
];

var result = data.filter(x => x.category.some(y => y.value == "mundial"));
console.log(result);
