How to destroy an object in javascript?

Question

I am wondering how to properly destroy an object in Javascript that contains an array among other data.

For example (this is the initial state of the object):

acme.models.nomination = { recipients : [], // array will be added to later. awardType: {}, // this object will be filled out later. privacy: 'private', ... }; 

The application uses the nomination.recipients object, as well as other data elements. Is it enough to do the following to clear the complete object when it is finished with it:

 acme.models.nomination = {}; 

or is it better (or overkill):

 acme.models.nomination.privacy = undefined; acme.models.nomination.awardType = {}; acme.models.nomination.recipients = {}; acme.models.nomination = {}; 

I think that the previous statement (i.e. acme.models.nomination = {} ) is enough, since it actually makes all the content inaccessible and therefore has the right to garbage collection. However, I would like to get other people's opinions on this. BTW, the answer can be given in the modern browser context, say post-Jan-2012 browsers, since I know that memory management was a bit inconsistent in the past.

Answer 1

I think delete -Operator is what you are looking for:

 delete acme.models.nomination;
