Performance is a very important aspect of every web application.
Web page should be loaded as quickly as possible and the animation should flow smoothly.
People are very sensitive to any kind of motion. For any kind of visual change on the screen, like scrolling, hover effect, opening the sidebar etc., the browser is going to render a new frame onto the screen. When rendering of the frame takes longer, the frame rate drops, and it negatively impacts the user experience.
Low frame rate will create a poor user experience. For this to happen, there doesn’t need to be some complex animation, it can happen with just a regular page scrolling!
I am pretty sure that you already had experience with websites that have a low frame rate, which causes that “laggy” animation? You click on something, open the sidebar and the whole page is lagging. Or even worse, you might have noticed that you have a laggy experience when scrolling the web page. Scrolling doesn’t seem like something you had to think about from the performance perspective, but you should. Therefore, in this course we will be talking about fixing the performance issues and so, you might expect that this course is about JavaScript&but surprisingly – it’s not. This course is about CSS. A lot of developers think that as long as JavaScript runs well, there’s nothing else left to do for the performance optimization. JavaScript has a great impact on the performance of the website, however CSS is unjustly neglectred in this area. In many situations CSS might be the only problem.

This is the course about speed performance more relevant and updated. I had some myths that this course helped me to understand better practices to improve how to work with html, css, javaScript and assets on the webpages to get a better performance. Even some explanations are very technical. It helped me to understand better some metrics when I inspect on Chrome the websites as FCP and the process of loading.

Provides a good, practical overview of browser and optimization concepts in just one afternoon. Really appreciate the focus on what the browser is doing and how to discover it in DevTools. Videos are all concise and informative; and while they don’t dive deeply into any one area, you’ll walk away with the high level knowledge you need to dig deeper on your own.
