Advanced React.js Performance

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.
