1. This is the functional component, there is no life cycle of pure components, inheriting components components have life cycle and internal state
2.components and containers are react components, but here components generally refers to pure components, that is, there is no internal state. The data displayed on the page comes from the parent component, that is, the containers component. Containers handles complex logic and data processing and passes the data to the child components through props. A simple example. A containers that shows the components of todolist is responsible for getting todolist through ajax. Pass it to the pure presentation components component
