Difference between derive and proxyWithComputed?

[jeffjose]

It sounds like both derive and proxyWithComputed can be used to create new attributes that respond to changes in the original state, but sounds like there's a subtle difference?

[wobsoriano]

derive can create a new proxy, whereas proxyWithComputed can only attach properties to the self-proxy.

Per Daishi, use derive first, and only reach out proxyWithComputed if something doesn't work as expected.
