Wren is a small, fast, class-based concurrent scripting language
Think Smalltalk in a Lua-sized package with a dash of Erlang and wrapped up in a familiar, modern syntax.

loxcraft: a compiler, language server, and online playground for the Lox programming language
Bob Nystrom also has a blog, and his articles are really well written (see his post on Pratt parsers / garbage collectors). I'd also recommend going through the source code for Wren, it shares a lot of code with Lox. Despite the deceptive simplicity of the implementation, it (like Lox) is incredibly fast - it's a great way to learn how to build production grade compilers in general.

Are they all like this?
If you want a pure C99 (sadly not C89 like Lua) immensely fast embeddable language pure interpreter, wren is a great language with excellent features like overload by arity. There is a huge maturity gap between the languages tho.

Most important language features not touched in the book "Crafting Interpreters"?
Check out the source to Wren: https://wren.io. It’s from the author of Crafting Interpreters and builds directly on what’s discussed in the book (essentially a more complete Lox) and adds several additional types, including an array.
What are some alternatives?
When comparing ChakraCore and Wren you can also consider the following projects:
V8 - The official mirror of the V8 Git repository
Lua - Lua is a powerful, efficient, lightweight, embeddable scripting language. It supports procedural programming, object-oriented programming, functional programming, data-driven programming, and data description.
Duktape - Duktape - embeddable Javascript engine with a focus on portability and compact footprint
nelson - The Nelson Programming Language
ChaiScript - Embedded Scripting Language Designed for C++
