To find a value in an array of objects in JavaScript, we use the filter method.

For instance, we write

const people = [
  { name: "bob", dinner: "pizza" },
  { name: "john", dinner: "sushi" },
  { name: "larry", dinner: "hummus" },
];
const filterted = people.filter((person) => {
  return person.dinner === "sushi";
});

to call people.filter with a callback that checks if the items in people has dinner property equal to 'sushi' and return them in a new array.
