Gain a thorough understanding of React’s new component style and learn to use the hooks API to write simpler and more elegant React code.

The core purpose of a React component is to define the displayed view and bind it to the code that drives its behavior. React’s functional components distill this down to the simplest possible profile: a function that receives properties and returns a JSX definition. Everything required for behavior is defined within the function body, and the class-related parts of object-oriented components are dropped.

Functional components are capable of performing all the work of a class-based component beginning with React 16, via the “hooks” API.
