Setting your UI components in motion adds a lot more than just pizzazz. Animation can convey interactivity, progress, and accomplishment, giving your users confidence that the system is working and they're in control. Let's add to our tool belts some fades, slides, expands, pops, and pauses that can feel at home in even the most buttoned-up business app, even when you have little time to spare. We'll explore real examples and common uses of each type of animation, how to build them, and how to build your UI components so it's easy to add them later. Examples will use JavaScript and React Native Reanimated for mobile and web, but to describe practices that can quickly enhance any front-end.
