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 be able to do this in pure JavaScript.

For example I'd have an object like this...

spy = { id: 007, name: "James Bond", age: 31 }; 

and the object would look like this after...

spy = { id: "redacted", name: "redacted", age: "redacted" }; 

Here is what I have to start with

var superSecret = function(spy){   // Code Here } 

This shouldn't create a new spy object but update it.

Answer 1

try

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

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; }, {})
