How to set all values of an object to null in JavaScript?

Question

I need to set all properties of some object to null. But the object can be very big, so I can\'t just do it one by one.

Another way of doing it, using Array.reduce. It does not overwriting the existing object. This only works if the object only have simple values.

const newObj = Object.keys(originalObj).reduce(
  (accumulator, current) => {
    accumulator[current] = null; 
    return accumulator
  }, {});
