specify an array of keys you want and an array of objs, should return an array of objects with only specified keys

getKeys.js

const objects = [
  {
    a: 'a',
    b: 'b',
    c: 'c'
  },{
    a: 'a',
    b: 'b',
    c: 'c'
  },{
    a: 'a',
    b: 'b',
    c: 'c'
  }
];
//  I only want these keys
const keysIWant = ['a', 'b'];

const getSanitizedObjects = () => {
  //  Expected:
  //  getSanitizedObjects[0] -> { a: 'a', b: 'b' }
  
  //  naive approach:
  return objects.map(obj => {
    return {
      a: obj.a,
      b: obj.b
    }
  })
};

const objects = [
  {
    a: 'one',
    b: 'two',
    c: 'c'
  },{
    a: 'three',
    b: 'four',
    c: 'c'
  },{
    a: 'five',
    b: 'six',
    c: 'c'
  }
];

const extract = (x, xs) => {
  return x.map(y => {
    return xs.map(z => ({ [z]: y[z] }))
  })
}


const extracted = extract(objects, ['a', 'b']);

console.log(extracted[1]);
// => { a: 'three', b: 'four' }

@jasonbellamy returns an array of arrays....

womp womp womp thanks for playing try again next time.

A solution that worked:

const extract = (x, xs) => {
    return x.map(y => {
      const obj = {};
      xs.map(z => {
        obj[z] = y[z];
      });
      return obj;
    });
  };
