React is the exciting web framework from Facebook. It runs Facebook.com and a host of other high-performing web applications, and is designed to facilitate three goals: performance, agility and scale.

React is a component-based front-end library that allows you to build applications out of a tree of small, testable, modular components. It features a diffing engine that makes DOM manipulation incredibly fast, faster even than vanilla DOM scripting.

Flux is an architectural pattern characterised by one-way data flow, immutability and message passing. In the course, we create a central data store and then pass messages to it, telling it how to change. Changes then flow into the component tree and update the DOM. This can seem intimidating at first but it quickly becomes natural. We use Redux for Flux, which is currently the best practice solution.

Our React training course is practical and you will build components and applications with real-world applicability, right from the start. We will build against tests from the end of day one, and design sensible component-based solutions using best practice. You will also gain an awareness of the wider JavaScript toolchain ecosystem including Node, Karma and Webpack.

JBI run public React courses in London and custom onsite courses at your UK or worldwide offices.

We can make our custom React training even more engaging and relevant by encouraging you to use their own corporate data.

React training courses are available for beginner, intermediate and advanced levels.

" I found the material on Redux extremely useful. There was a definite moment of clarity. The instructor was engaging + knowledgeable on topic. Even if it was off topic question was able to provide answer with examples that you could relate to for learning. Great instructor, great course."
