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.

How to set all properties at onc

Answer 1

If object contains child object, if you want to set all child object properties to null, recursive solution is below.

function setEmpty(input){

let keys = Object.keys(input);

    for( key of keys ){

         if(typeof input[key] != "object" ){
             input[key] = null;
         }else{
             setEmpty(input[key]);
         }
    }
    return input;
}
