Xstate: [Hacktoberfest] Memoization of properties!

[davidkpiano]

Bug or feature request?

Enhancement

Description:

For Hacktoberfest, I would love help adding a memoization decorator to certain computed get properties in StateNode, such as:

• .definition
• .config
• .on
• .after
• .tree
• .delays
• .resolvedStateValue
• .initialStateValue
• .initialState
• etc.

For some properties, caching is already done in an ad-hoc way (e.g., with __cache and idMap) but there's definitely better ways to do this.

(Feature) Potential implementation:

Take a look at something like typescript-memoize to guide you.

Is this issue already done @davidkpiano ?
In case it's not done, I'd like to take it.
