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

Native ES2019 one-liner

const data = {
  aaa: 111,
  abb: 222,
  bbb: 333
};

const filteredByKey = Object.fromEntries(Object.entries(data).filter(([key, value]) => key.startsWith("a")))

console.log(filteredByKey);
