- Making my Markdown Format package for Atom have zero external dependencies by compiling the Go code into JavaScript. That way there's no need to install and point to the markdownfmt binary, making install easier. https://github.com/shurcooL/atom-markdown-format/commit/6b5f...

- Replacing JavaScript with Go code in Go Package Store, still a WIP PR because I need to figure out a `go get` difficulty, but aside from that it works perfectly well. https://github.com/shurcooL/Go-Package-Store/pull/18

- Various experimental things that run in the browser and perform operations that use existing Go code. For example: https://dl.dropboxusercontent.com/u/8554242/dmitri/projects/... https://dl.dropboxusercontent.com/u/8554242/dmitri/projects/...

- At work, I've created a small standalone project with a frontend UI that reused some common structs and html template code between the frontend and backend (ala node.js, except all in Go).

- Working on porting my small OpenGL game written in Go to run in the browser. The goal is to have the same Go code use OpenGL when on desktop, but use GopherJS and WebGL when compiling for the browser.

Basically, it lets me do all the things that one would normally be forced to use JavaScript for (i.e., frontend code) but without having to use JavaScript (I'm not good at it and I don't like it), while benefitting from Go compiler to catch errors, autocomplete, godocs, goimports, etc. It also allows me to import and use existing Go packages that perform non-trivial tasks.
