In this episode we build a parser that can handle every instruction that the VM currently supports.
=[ 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 the parser combinator system is turned on binary data. We learn how to specify and extract individual bits, Typed Arrays, ArrayBuffers and DataViews, and about important concepts like bit ordering.
=[ 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.

This mini series is all about binary. Over the course of the series, well be building a library that gives us precise control of every bit and operation.
Youll learn how the logical and arithmetic operations work, how different kinds of numbers are encoded, how to set, clear and toggle bits, and how we can create representations of structured binary data.
1. Bits
2. Operations
3. Unsigned Numbers
4. Addition
5. Zero Extension
6. Twos complement
7. Overflow Addition and Sign Extension
8. Shifting
9. Setting, Clearing, and Toggling Bits
10. Endianness
11. Structures
