Chapter 3. Data Flow and Life Cycle Events
In the previous chapter, we saw the power of JSX. JSX makes it easy to write the React components.
In this chapter, we will focus on the data flow between components and how to manage state and life cycle of components.
In this chapter, we will cover the following points:
- Data flow in React
- Props
- PropTypes
- State
- State versus props
- When to use state and props
- Component life cycle overview
- Component life cycle methods
At the end of the chapter, we will get familiar with the data flow in the React components and the ways of maintaining and managing state. We will also get used to the life cycle of a component and various life cycle hooks provided by React.
