V8

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

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

I used to have a site bookmarked with a table of all these functions, but the link is dead. Here's a matrix of Option and Result conversion functions. These become second nature once you have used Rust for any significant length of time, but it's useful to have a table reference.

For each of the below:

T is the value possibly contained in an input Ok Result or Some Option.
U is a new value created by transforming or replacing an input T. Note that when U appears in methods like map, U ?= T, for example by calling
