Did you know that React, the JavaScript library for building user interfaces, was developed by Jordan Walke, a coder over at Facebook?

Back in 2011, React made its debut on Facebook's newsfeed, and by 2012, it also made its debut on instagram too! React's primary goal was to improve the performance and efficiency of user interfaces, particularly in the context of dynamic and frequently updating content, which is common in social media applications.

Since then, React has gained widespread popularity in the web development community and is widely used for building user interfaces for various applications.
