In general I like to have the vendor's name before the product so it seems more trustworthy. This whole section is more like trivia, so there's no need to try to prune information.

I noticed that some information is removed; I think it's better to keep feature parity with the previous version.

Suggested change

	- [SpiderMonkey](https://spidermonkey.dev/), used in Firefox (and its forks), Servo, and Flow (and in MongoDB, CouchDB, and more).
	- [V8](https://v8.dev/), used in Chrome and in other Chromium-based browsers (and in [Node.js](https://nodejs.org/), [Deno](https://deno.com/), [Electron](https://www.electronjs.org/), and more).
	- [JavaScriptCore](https://docs.webkit.org/Deep%20Dive/JSC/JavaScriptCore.html), used in Safari and in other WebKit-based browsers (and in [Bun](https://bun.sh/).
	- Mozilla's [SpiderMonkey](https://spidermonkey.dev/), used in Firefox, Servo, and more. Other non-browser usage includes MongoDB, CouchDB, and more. This was the first _ever_ JavaScript engine, created by Brendan Eich at Netscape.
	- Google's [V8](https://v8.dev/), used in Chrome and Chromium-based browsers such as Opera, Edge, and Brave. Other non-browser usage includes [Node.js](https://nodejs.org/), [Deno](https://deno.com/), [Electron](https://www.electronjs.org/), and more.
	- Apple's [JavaScriptCore](https://docs.webkit.org/Deep%20Dive/JSC/JavaScriptCore.html) (also known as SquirrelFish/Nitro), used in Safari and other WebKit-based browsers. Other non-browser usage includes [Bun](https://bun.sh/).

There are two unrelated Chakras.

Suggested change

	- [Chakra](<https://en.wikipedia.org/wiki/Chakra_(JScript_engine)>), used in Internet Explorer and in Edge before it became a Chromium-based browser.
	- Microsoft's [Chakra](<https://en.wikipedia.org/wiki/Chakra_(JScript_engine)>) engine, used in Internet Explorer (although the language it implements is formally called "JScript" to avoid trademark issues). Earlier versions of Edge used a new JavaScript engine, confusingly also called [Chakra](<https://en.wikipedia.org/wiki/Chakra_(JavaScript_engine)>), before it became a Chromium-based browser.

Suggested change

	- [Hermes](https://github.com/facebook/hermes), optimized for [React Native](https://reactnative.dev/docs/hermes).
	- Meta's [Hermes](https://github.com/facebook/hermes), optimized for [React Native](https://reactnative.dev/docs/hermes).
