In this episode we're going to take a break from building functionality in the virtual machine and take a tour through the assembly language that this VM will support, and some features of the assembler - which will turn that assembly language into machine code.
=[ ℹ About ℹ ]=
This series is all about building a powerful virtual machine in JavaScript with the following features:
- A flexible, extensible, register-based virtual machine
- Support for signed, unsigned and floating point operations
- A call stack
- Interrupt capabilities
- Ability to do memory mapping for IO
- An assembly language with macro and module support
- A higher level, C like language. We'll use and expand the library from the parser combinators from scratch series
- And finally, to be able to take the whole thing into the browser and extend it to create a sort of fantasy console - an emulator for a machine that never existed

In this episode we dive into parsing recursive structures, and build a very simple functional language parser and interpreter.
=[ ℹ About ℹ ]=
During this series we will develop an understanding of the concept of parsing, and build our own parser combinator system from scratch. The system we build will be capable of parsing both binary and text data. Well make use of both object-oriented and function programming principles to develop an effective and intuitive library.
