Animating URLs with Javascript and Emojis
You can use emoji (and other graphical unicode characters) in URLs. And wow is it great. But no one seems to do it. Why? Perhaps emoji are too exotic for normie web platforms to handle? Or maybe they are avoided for fear of angering the SEO gods? Whatever the reason, the overlapping portion on the Venn diagram of "It's Possible v.s. No One Is Doing It" is where my excitement usually lies. So I dec

GitHub - camsong/You-Dont-Need-jQuery: Examples of how to do query, style, dom, ajax, event etc like jQuery with plain javascript.
Frontend environments evolve rapidly nowadays and modern browsers have already implemented a great deal of DOM/BOM APIs which are good enough for production use. We don't have to learn jQuery from scratch for DOM manipulation or event handling. In the meantime, thanks to the spread of frontend libraries such as React, Angular and Vue, manipulating the DOM directly becomes anti-pattern, so that jQu

It is the sort of thing that usually goes unnoticed, but when your readers are developers, there's a better chance they notice and appreciate it.
