NoLoJS: Reduce the JS Workload with no- or lo-JS

For years, JS has been the web's workhorse. If HTML and CSS couldn't do something, you used JS. And that has really helped push user experiences, and HTML and CSS, forward! But as HTML and CSS gain capabilities, we should hand-over the JS workload where possible.

Nothing against JS, but it has better things to do than manage accordions or offscreen nav menus...

Aaron T. Grogg (He/Him) became addicted to the web in 1998. He has since developed a passion for improving the user experience through web performance optimization, as well as researching, imagining, testing, implementing, mentoring, and serving as a technology advocate. When not noodling with web stuff, Aaron can usually be found hiking, biking, gardening, traveling, reading and/or just hanging-out and enjoying life with his wife, friends and family.
