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

Just change filter to omitBy

const data = { aaa: 111, abb: 222, bbb: 333 };
const result = _.omitBy(data, (value, key) => !key.startsWith("a"));
console.log(result);
