Crystal's Interpreter (2021)
it's had an IRB-like REPL for years. It just wasn't built into the language. Admittedly it was limited compared to IRB but it was more than enough to test out quick ideas.
It's called ICR: Interactive Crystal
https://github.com/crystal-community/icr
the first release was back in 2017

Simple Jupyter kernel for Crystal with 140 lines
I wrote a Crystal kernel for Jupyter, just a modified bash_kernel, 140 lines of code, but it was tiring because I don't have enough Python ability. icrystal is the widely used Jupyter kernel for Crystal, which uses ICR . On the other hand, this crystal_kernel uses the official crystal interpreter.

This year in Servo: over 1000 pull requests and beyond
I thought it would be a fun weird project to make Servo work with MS' abandoned JavaScript engine:
https://github.com/chakra-core/ChakraCore
Of course it is written in C++ and you'd probably want a pure Rust browser. But it is sad seeing that fairly complete open source JIT JavaScript engine sit and rot.

Roll your own JavaScript runtime, pt. 3
Not to forget the engine Charka: https://github.com/chakra-core/ChakraCore
The only bit of the old Edge that had its source emancipated. It was/is? quite performant.

Have you deployed Microsoft Todo to end users? How did you deploy it?
As a Linux user, I very much think Microsoft should have continued Trident and Chakra. Apple also should have continued releasing Safari for Windows. Our web QA setup was entirely built around Macs back then, but it was great to be able to test sites with Safari on Windows, and to have another responsive browser on Win32.

The Javascript Engine
Edge was initially using Chakra but has been rebuilt using Chromium and the V8 engine.

Crystal's Interpreter (2021)
https://github.com/chakra-core/ChakraCore/wiki/Architecture-...
I've found the source code to be quite readable too - albeit from a bug-finding perspective, not a strictly pedagogical one.

Exploring React Native’s new architecture
Furthermore, the new architecture decouples the JavaScript interface from the engine, enabling the use of other JavaScript engines such as Hermes, V8, or Chakra.

Enumerating and analyzing 40 non-V8 JavaScript implementations
I am astonished at the omission of ChakraCore, open sourced by Microsoft but sadly abandoned by them after they switched Edge to Chromium: https://github.com/chakra-core/ChakraCore. But it looks like it’s still chugging along as a community effort rather than being completely abandoned.
