How to find out which place in an object a given property is in Javascript

For example, if I have an object like:

{"angeredoutsidecontrol":"1","difficultiespileup":"2"}

And then later in a for loop I can access the key of angeredoutsidecontrol , how can I get the value returned as 0, which would represent which place in the object this key is?

var myMoods = ["angeredoutsidecontrol","difficultiespileup"];

and 

myMoods.indexOf( 'angeredoutsidecontrol' )

gives you position in your list

The order of JSON objects is not maintained, so you can't do this.

There is no guaranteed order for keys of an object.

Definition of object from an old - but still effective in this case - documentation:

4.3.3 Object

An object is a member of the type Object. It is an unordered collection of properties each of which contains a primitive value, object, or function. A function stored in a property of an object is called a method.

If order really matters to you, use array instead. For example:

[{ "angeredoutsidecontrol": "1" }
 { "difficultiespileup": "2" }];
