What situations would be good to use context?
When more than one component in a deeply nested tree need to access some data in our app, conext will be a good choice.

If you need to pass a prop down 1 or 2 levels, is context necessary?
No, it's not necessary. Applying context makes component's reuse more difficult.

Can you pass a component instance as a prop to avoid the need for context?
Yes you can, this is what's called component composition.

Can you write your own components that accept render props?
Yes I can


No seriously
We can use Context.Consumer to do that

const colorContext = React.createContext ({
    color: 'blue'
});
export default colorContext;

import colorContext from './......
.
.
.
<colorContext.Consumer>
 {function renderProp() {
 <div />
 }
 </colorContext.Consumer>
