use Facebook's create-react-app scaffolding to quickly build a react development environment (Ant.design,redux ...). ) The "scaffolding" in the programming field refers to a kind of tool that can quickly build a "skeleton" of the project scaffolding. For example, most react projects have src,public,webpack profiles, and so on, and the SRC directory contains components directories, and so on. Each time you create a new project, these fixed file directories are created manually. The role of scaff
