Use a string to define a React element

Take a simple example:

/ / We can assign a string'p'to a variable, such as: import React from 'react'const MyComponent =' p'function App () {return (I am inside a {'} element)}

React.createElement is called internally in React and this string is used to generate the element.

Alternatively, you can explicitly define component to determine what is rendered, such as:

/ / define a MyComponentfunction MyComponent ({component: Component = 'paired, name, age, email}) {return (Hi {name} You are {age} years old Your email is {email})}

Applicable method:

Function App () {return ()}

In this way, you can also pass in a custom component, such as:

Function Dashboard ({children}) {return ({children})

)} function App () {return ()}

If you come across dealing with a similar class of elements or components, you can abstract it in this custom way to simplify your code.

Let's take a realistic example:

For example, we need to make a requirement for packing goods, either individually or in batches, and we can write custom components according to the common points:

Import React from 'react'import withTranslate from' @ components/withTranslate'import PackComponent from'. / PackComponent'import usePack, {check} from'. / usePack'let PackEditor = (props) = > {const packRes = usePack (props) return ()} PackEditor = withTranslate (PackEditor) PackEditor.check = checkexport default PackEditor

In this way, it can be used flexibly in different business modules, which is very convenient.
