Learn Performance: A New Primer for Building Faster Sites
Web performance has a direct impact on user experience, yet many developers only start to dig into it once something has already gone wrong. The initial version of Learn Performance, released today, is designed to change that by offering a structured, technical entry point for developers who want to understand how to optimize their pages.
The course is the newest addition to the Learn series on web.dev. It targets an audience that may be new to performance, but it moves quickly into the practical details of making web pages faster. The material was written primarily by Kevin Farrugia, with additional modules by Jeremy Wagner, and reviewed by Rachel Andrew and Barry Pollard.
The modules are structured so that beginners can progress from start to finish, while developers with more experience can jump directly to the specific topics they need. Instead of prescribing a set of arcane rules, the course emphasizes the core concepts you'll need to make informed decisions about your own sites.
It's also worth noting that this is just the initial offering. The course is still growing, and the team is actively soliciting feedback from the community via the public issue tracker. This includes not just bug reports and typo corrections, but requests for entire new modules you'd like to see covered.
