Differences between: init-state vs: state at build function

Question

I understand that you can initiate the state of a component by passing the map as the keyword value: init-state. But, passing this map as the value of the keyword: state, for example, between a component and its child component, can they now share the same state? This is it? Thanks.

Answer 1

The difference is when the childs state is set.

• :init-state set only once when the component is mounted.
• :state set on each render.

Therefore :init-state should be used (as the name implies), initialize the state. On the other hand :state used to set a state that changes over time.
