Built-in React Components

React exposes a few built-in components that you can use in your JSX.


Built-in components

  • <Fragment>, alternatively written as <>...</>, lets you group multiple JSX nodes together.
  • <Profiler> lets you measure rendering performance of a React tree programmatically.
  • <Suspense> lets you display a fallback while the child components are loading.
  • <StrictMode> enables extra development-only checks that help you find bugs early.
