React Under the Hood: Understanding React’s UI Rendering Process

Anthony Garritano   

Most of us have at least dabbled with the shiny frontend technologies that have come out in the past decade. But do we know how they really work? In this talk we’ll examine how React implements a Virtual DOM to quickly render changes to the user interface.

By the end of this talk the audience will…

  1. Know the basics of UI rendering with JS through a Virtual DOM.
  2. Understand React’s Reconcilliation, the process of determining which Virtual DOM nodes should be turned into real DOM nodes.
  3. Have more confidence about the frontend technology decisions they make through an understanding of how they work.
