First I would load up a throttle/debounce function of some kind. And you can also do things like handle tab visibility, as I do in this fiddle to manage a canvas snow animation. I’m doing that at the time of this writing to keep Spider-Man from being scaled down in a smaller browser. It can also do nifty things like set the width of a canvas so that it’s always the same width as your header. A resize function can adjust the height of stubborn elements or add classes to something as the browser crosses a media query breakpoint.
For example, there might be a responsive navigation menu that needs to disappear or become a toggle in the mobile view. I try to handle resize with CSS alone, but there are times when JavaScript needs to step in. That’s been fine for a while, but recently I found a need to upgrade things. It’s a good way to correct the heights of things or add a class when the window hits a certain size.

To successfully complete this tutorial, you will need the following: You will also implement React Observer in your own front end code and test for browser support.
In this tutorial, you will learn about basic usage of React Observer. This is more and more frequent with modern single-page apps. There’s also another use case for the Resize Observer API that the window’s resize event can’t help us with: when elements are added or removed from the DOM dynamically, influencing the size of the parent element. In other words, using window.resize is often wasteful because it informs us of every viewport size change, not just when an element’s size actually changes. This can easily lead to performance problems due to the large amount of triggered event. Up until this point, we’ve had to rely on the global window.resize event to listen for resize events and check if certain elements have changed size. The most frequent reason for an element’s size to change is when the viewport is resized or the device’s direction changes between portrait and landscape. It allows for elements to be notified when their size changes. Resize Observer is a new JavaScript API that’s very similar to other observer APIs like the Intersection Observer API.
