How to filter specific key + values in Javascript

I am working with the swapi API. I want to return an object but only specific entries. For example; Obj = { name: "Luke", age: 10, gender: "male"} But I specifically want to return a new object which is the name and gender with it's key name and value. My goal is to return them into a table but possibly have the option to have advanced filter. So user can return for name and age or more entries.

const results = people.filter(person => person.age === 10 && person.gender === 'male');

const results = people.filter(person => person.age === 10 && person.gender === 'male');

this returns an array of person objects that match the criterea

I'm not sure, I don't want the gender male and want the results of the key gender So not just the values but it's actually key so I can print the key in a table header

Example currenlt in my react app, i search for the characters name, "luke" which will render a table with luke skywalker in the name column and other properties in the object in api How do i only return specific columns? the user does not need to see all the object properies as that would be a big table (over scrolling etc) @MarkBoots

const filtered = array.map(entry => {
  const { name, office } = entry; /* deconstruct the object's specific keys */
  return { name, office } /* return an object with only those key/value pairs */
}

const filtered = array.map(entry => {
  const { name, office } = entry; /* deconstruct the object's specific keys */
  return { name, office } /* return an object with only those key/value pairs */
}

i forgot all about destructering Thank you! Well that would be the same hard coding, i think what I should do is to render everything and hide them using css That's anyway I appreciate it
