React
A JavaScript library for building user interfaces
Developed at Facebook in 2011
A Growing and Healthy Community and Ecosystem
Client
- Components
(piece of the UI)
- encapsulated
- manage their own state
- compose them to make complex UIs
The Virtual DOM
The Problem:
DOM manipulation
(a lot slower than most JavaScript operations)
The Virtual DOM
- The entire virtual DOM gets updated.
- The virtual DOM gets compared to what it looked like before you updated it. React figures out which objects have changed.
- The changed objects, and the changed objects only, get updated on the real DOM.
