Why can't the module be found?

Question

React

Installed react
in script: import React, { PureComponent, Fragment } from 'react'
react is highlighted with hint:
Could not find module declaration file 'react'. "c:/frontend/node_modules/react/index.js" has an implicit type of "any".
Try "npm install @types/react" if possible, or add a new declaration file (.d.ts) containing "declare module 'react';"
I tried npm install @types/react, it helped, but what is this @types/react?
