How to filter keys of an object with lodash?

Question

I have an object with some keys, and I want to only keep some of the keys with their value?

I tried with filter:

Answer 1

A non-lodash way to solve this in a fairly readable and efficient manner:

function filterByKeys(obj, keys = []) {
  const filtered = {}
  keys.forEach(key => {
    if (obj.hasOwnProperty(key)) {
      filtered[key] = obj[key]
    }
  })
  return filtered
}

const myObject = {
  a: 1,
  b: 'bananas',
  d: null
}

const result = filterByKeys(myObject, ['a', 'd', 'e']) // {a: 1, d: null}
console.log(result)
