Component Specification

Question 1

render()

Answer 1

Render the component to element

returns: ReactElement or false

Note: Should be pure. This means idempotent and it doesn’t interact with the browser (e.g. setTimeout)

Question 2

getInitialState()

Answer 2

Get initial value of this.state

returns: object

Question 3

getDefaultProps()

Answer 3

If a prop isn’t on this.props, then add in the default

returns: object

This is called before any instances are created, so you can’t depend on this.props in it
