all comments/suggestions on examples/react-native/__tests__/js/realm-database/schemas/mixed-tests.jsx also apply to this file

[mongodben]

still applies for remaining nit https://github.com/mongodb/docs-realm/pull/2411/files#r1061575928

outside of scope of this PR, but would be good to have example of using mixed type with a collection.

[mohammadhunan-dev]

Interesting idea, I'm not opposed to it, but don't necessarily want to bulk up this page. Maybe a note saying for additional examples, see ?

[mongodben]

what would that note point to?

[mohammadhunan-dev]

Possibly an "Additional Examples" page like we used to have for C#?

[mongodben]

nice work! i like the way you handled the @realm/react-ification of the examples.

couple small suggestions/nits throughout.

and then some larger comments about how the data type is described that fall outside of the scope of this PR, but should probably be addressed. could be good work for @krollins-mdb to learn more about the SDK.

Suggested change

	useEffect(() => {
	// Add data to the Realm when the component mounts
	// Add data to the Realm when the component mounts
	useEffect(() => {

nit: think it'd be clearer if this comment before the hook.

[mohammadhunan-dev]

I like it where it is because the comment is directly above the write transaction where you add the data

[mongodben]

lgtm.

couple little things to fix and 1 open question, but nothing blocking.

What we are missing here is a nice method called Realm.Object.getPropertyType(propertyName:string). This will return the underlying property type as a string. This is useful when trying to do some type checking on a mixed property.
The cat example could use this to logically depict how it should interpret the given birthday type.
