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.

also a milestone year for the front-end community.React IntroductionWhat exactly is react? Facebook simply and quietly defines it as a "JavaScript library for building the UI."

To understand react, you should know that all react components have a render () method (if a component written in the function method is used, all the code in the function will be inserted to render () ). When the ReactDOM. render (element, container, [callback]) method is executed, the following steps are performed: All

React originally came from a Facebook-based advertising system project, where front-end development was a huge challenge in the implementation of the project, and the code became bloated and messy and difficult to maintain. So, they decided to throw away many so-called "best practices" and rethink the way the front-end interface was built, so there was react.React brings a lot of pioneering ideas to build the front-end interface, although one of the m
