Looping through an object and changing all values

Question

I\'m having trouble looping through an object and changing all the values to something else, let\'s say I want to change all the values to the string \"redacted\". I need to

Answer 1

Use a proxy:

function superSecret(spy) {
  return new Proxy(spy, { get() { return "redacted"; } });
}

> superSecret(spy).id
< "redacted"

Answer 2

You can also go functional.

Using Object.keys is better as you will only go through the object properties and not it's prototype chain.

Object.keys(spy).reduce((acc, key) => {acc[key] = 'redacted'; return acc; }, {})

Answer 3

This version is more simple:

  Object.keys(spy).forEach(key => {
    spy[key] = "redacted");
  });

Answer 4

try

var superSecret = function(spy){
  Object.keys(spy).forEach(function(key){ spy[key] = "redacted" });
  return spy;
}

Answer 5

A nice solution is using a combination of Object.keys and reduce - which doesn't alter the original object;

var superSecret = function(spy){
  return Object.keys(spy).reduce(
    (attrs, key) => ({
      ...attrs,
      [key]: 'redacted',
    }),
    {}
  );
}

Answer 6

var superSecret = function(spy){
    for(var key in spy){
          if(spy.hasOwnProperty(key)){
               //code here
               spy[key] = "redacted"; 
            }
     }
   return spy;    
}
