import { useSyncExternalStore } from "react";
// For more on the useSyncExternalStore hook, see https://react.dev/reference/react/useSyncExternalStore
// The code is almost identical to the source code of zustand, without types and some features stripped out.
// Check the links to see the references in the source code.
// The links are referencing the v5 of the library. If you plan on reading the source code yourself v5 is the best way to start.
// The current v4 version contains lot of deprecated code and extra stuff that makes it hard to reason about if you're new to this.

A list of JavaScript engines, runtimes, interpreters

V8 is Google’s open source high-performance JavaScript and WebAssembly engine, written in C++. It is used in Chrome and in Node.js, among others. It implements ECMAScript and WebAssembly, and runs on Windows 7 or later, macOS 10.12+, and Linux systems that use x64, IA-32, ARM, or MIPS processors. V8 can run standalone, or can be embedded into any C++ application.

SpiderMonkey is Mozilla’s JavaScript and WebAssembly Engine, used in Firefox, Servo and various other projects. It is written in C++, Rust and JavaScript. You can embed it into C++ and Rust projects, and it can be run as a stand-alone shell. It can also be [compiled](https://bytecodealliance.org/articles/making-javascript-run-fast-on

VSCode config to disable popular extensions' annoyances (telemetry, notifications, welcome pages, etc.)
// I'm tired of extensions that automatically:
// - show welcome pages / walkthroughs
// - show release notes
// - send telemetry
// - recommend things
//
// This disables all of that stuff.
// If you have more config, leave a comment so I can add it!!

Note: I have moved this list to a proper repository. I'll leave this gist up, but it won't be updated. To submit an idea, open a PR on the repo.

Note that I have not tried all of these personally, and cannot and do not vouch for all of the tools listed here. In most cases, the descriptions here are copied directly from their code repos. Some may have been abandoned. Investigate before installing/using.

The ones I use regularly include: bat, dust, fd, fend, hyperfine, miniserve, ripgrep, just, cargo-audit and cargo-wipe.
