Reversing an Object.entries conversion

Question

I am using Object.entries in order to get some values out of a nested object and filter it.

obj = Object.entries(obj)
  .filter(([k, v]) => {         


        

Answer 1

If you know exactly which entries you want to exclude, you can use object deconstruction combined with spreading:

function clean(obj) {
  const { unwanted1, unwanted2, ...wanted } = obj;
  return { ...wanted };
}

For some cases, this might be the cleanest solution.
