Facebook, LinkedIn Reflect on 2015: The Year in Open Source
Last year, React and HHVM became Facebook's first projects to generate 10,000 stars. Stars are a way for developers to keep track of repositories that they find interesting on GitHub. Abernathy said three additional projects joined the 10,000-stars ranks in 2015, while React tripled in popularity to become Facebook's first project with more than 30,000 stars. Facebook's open-source projects topping 10,000 stars include: React, with 33,000 stars; React Native, with 24,000 stars; Pop, with 13,500 stars; HHVM, with 13,000 stars; and Immutable.js, with more than 10,000 stars.
