Retrieve the property names of an object using the `Object

When I work with frameworks like Phaser.js, I find it helpful to use the console to discover possible properties of objects by using:

Object.getOwnPropertyNames(myObject)

However, I've noticed that some properties don't appear in the console, likely because they are not "own" properties of the object. Is there a way to make these properties show up in the console as well?

I'm essentially looking for a method like:

Object.getAllPropertyNames(myObject)

If anyone could offer assistance, I would greatly appreciate it! I'm still new to JavaScript :)

Answer №1

When utilizing Google Chrome's DevTools, you have the ability to access all properties of an object simply by invoking dir(myObject):

Answer №2

Utilize a for ... in loop to iterate through all the properties. This method will also traverse through any "parent" properties.

// sample data
var o = { 
  a: "a1",
  b: "b1"
}

var parent = { 
  c: "c1",
  d: "d1"
}
// assigning parent for illustration purposes only
Object.setPrototypeOf(o, parent);
  
// looping through all properties
for (key in o)
{
  console.log('property "' + key + '" with value "' + o[key] + '"');
}

Nested example:

var game =  {
  stage :{
    test1 : 'v1',
    test2 : 'v2'
    
  }
   
}

for (key in game.stage) 
 { console.log(key + '" with value "' + game.stage[key] + '"'); }
