In React, looping through rendering components can be achieved by using the map method of an array. The specific steps are as follows:<\/p>\n

    \n
  1. First, create an array containing the data of the components that need to be rendered.<\/li>\n
  2. Traverse the array using the map method, returning a component instance for each element and storing it in a new array.<\/li>\n
  3. Finally, render the component instances stored in the new array onto the page.<\/li>\n<\/ol>\n

    The sample code is as follows:<\/p>\n

    import<\/span> React<\/span> from<\/span> 'react'<\/span>;\r\n\r\nconst<\/span> ComponentList<\/span> = (<\/span>) => {\r\n  const<\/span> data = [1<\/span>, 2<\/span>, 3<\/span>, 4<\/span>, 5<\/span>];\r\n  \r\n  return<\/span> (\r\n    <div<\/span>><\/span>\r\n      {data.map(item => (\r\n        <Component<\/span> key<\/span>={item}<\/span> data<\/span>={item}<\/span> \/><\/span>\r\n      ))}\r\n    <\/div<\/span>><\/span><\/span>\r\n  );\r\n};\r\n\r\nconst<\/span> Component<\/span> = ({ data }<\/span>) => {\r\n  return<\/span> <div<\/span>><\/span>{data}<\/div<\/span>><\/span><\/span>;\r\n};\r\n\r\nexport<\/span> default<\/span> ComponentList<\/span>;\r\n<\/code><\/pre>\n
    In the example above, the ComponentList component uses the map method to loop through the data array, returning instances of the Component component, storing them in a new array, and finally rendering the component instances from the new array onto the page.<\/p>\n","protected":false},"excerpt":{"rendered":"
