React is fast, really fast, thanks to its virtual DOM. However, React does perform a lot of expensive computations on the main UI thread. The only semblance of a separate thread is a web worker - a feature from the HTML5 hype-era; often used to perform artificial image manipulations in fancy demos. In this talk, we will look at ways create a web worker based renderer for React, and analytically compare its performance to a normal react operation. We will also explore the limitations of this approach and see how we can use this in our existing applications.Show more
