User extensions are a mechanism that allow users to write GNOME extensions in Javascript, similar to how Chrome and Firefox extensions work. […] I'm not sure that disabling user extensions actually disables the Javascript engine completely, but it definitely minimizes it to the least possible scope. Gnome Shell itself is largely written in JavaScript. From https://gjs.guide/extensions/overview/architecture.html#shell https://gjs.guide/extensions/overview/architecture.html#shel... > GNOME Shell's JavaScript codebase uses these libraries to create the user interface you interact with every day, organized into modules. A number of these modules are re-used throughout GNOME Shell and are commonly used in extensions I wrote a tiling window manager extension for myself in 2010. At least back then it was a very weird JavaScript environment and I didn’t enjoy programming for it. It was best to write all the code for browser and use dependency injection with small Gnome Shell specific parts because debugging in the browser was so much easier.

There's a typo/thinko there too? Should be true not false.

Good observation. Turning off extensions is where OP lost me. In the last year, the single biggest quality of life improvement for me has been discovering the Argos[0] extension, which basically lets you put whatever text/menus you want in the top bar by writing scripts that print to stdout. To save space, I hid the dock (I use [1] as a replacement alt-tab), so the top bar is the only piece of screen that isn't OS chrome. On my top bar right now I have the time in four time zones (including the ever-important UTC to save a mental calculation when logging at logs), the name of the current Wifi access point, and some VPN details gleaned using a combination of ip r, ping, nc, and curl. Another extension shows free RAM. I look at them dozens of times a day.

  JavaScript in Gnome shell is not doing any heavy lifting... all such things are done in C code.
