In this session we create a comment component to explore how to create components that only render text. In previous versions of we had to wrap our text in needless <span> or <div>, we will see how React 16 removes the unneeded structure. impo…

React loves svg just as much as it loves html. In this lesson we cover how simple it is to make SVG components in ReactJS. Creating SVG components with React allows you to inline SVG. Inline SVG has an advantage that it can be styled with CSS just li…

By default the React Component Tree directly maps to the DOM Tree. In some cases when you have UI elements like overlays or loading bars this can be limiting. React 16 therefor ships with the new portal feature allowing you to attach parts of the Com…

Learn to write components that render differently on iOS and Android, but present the same API. First, we'll use the Platform module to change behavior based on the platform. Then, we'll use the platform-specific file extensions, .ios.js and .android…
