[removed] filter() for Objects

Question

ECMAScript 5 has the filter() prototype for Array types, but not Object types, if I understand correctly.

How would I implemen

Answer 1

I use this when I need it:

const filterObject = (obj, condition) => {
    const filteredObj = {};
    Object.keys(obj).map(key => {
      if (condition(key)) {
        dataFiltered[key] = obj[key];
      }
    });
  return filteredObj;
}
