Compatibility was another factor: this rewrite has no major breaking API changes.

In this chapter, you'll learn about the major changes introduced in React 16:

  • The major changes made to the reconciliation internals, and what they mean for React projects, going forward

  • Confining errors to the sections of your application by setting error boundaries

  • Creating components that render more than one element and components that render strings

  • Rendering to portals
