Johannes Stein, Freelance, Berlin — React For Game Development

Using React for game development may not seem like an obvious choice at first. With React itself being compared to the Doom 3 game engine at F8 2014, we may not find ourselves in such a bad spot. We will take a look at how games are usually structured. Then we will examine different concepts in game development such as the entity-component pattern, object pools, and how we can implement them in React. At the end, we'll put it all together into a React-powered game.
