The count of contributions (summary of Pull Requests, opened issues and commits) to public repos at GitHub.com from Tue, 06 Dec 2016 17:06:46 GMT till Wed, 06 Dec 2017 17:06:46 GMT.
Only first 1000 GitHub users according to the count of followers are taken. This is because of limitations of GitHub search. Sorting algo in pseudocode:
githubUsers
.filter(user => user.followers > 1000)

Performance is one of the reasons why React.js is so popular for building complex, highly interactive web applications. It became the go-to library for developers who don’t like to make compromises for technical reasons when building awesome user experiences. However even with React.js it still can be easy to hit it’s performance limits.
In this lightning talk Daniel will go beyond the basics of shouldComponentUpdate and immutable data structures and will discuss how to correctly instrument, measure and optimize performance in complex React apps. He will help you understand the overhead of different parts of the React component lifecycle, how some of it’
