Why did we build React?

There are a lot of JavaScript MVC frameworks out there. Why did we build React and why would you want to use it?

React isn’t an MVC framework.

React is a library for building composable user interfaces. It encourages the creation of reusable UI components which present data that changes over time.

React doesn’t use templates.

Traditionally, web application UIs are built using templates or HTML directives. These templates dictate the full set of abstractions that you are allowed to use to build your UI.
