In this episode we'll create a Parser class and implement map, a method that will allow us to apply arbitrary structure as we parse.
We'll also build more general parsers like letters and digits, as well as combinators like choice and many.
=[ 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. We'll make use of both object-oriented and function programming principles to develop an effective and intuitive library.

![EXTRA: Chain Tricks For Sequential Parsing - Parser Combinators From Scratch
In this episode we discover how the .chain() method (one of our monadic ingredients) allows us to turn deeply nested, contextual parser descriptions into flat, readable flows - much the same as async/await does for promises!

![Implementing Stack Mechanics (16-Bit VM in JavaScript 004)
In this episode, we create an implementation for the stack mechanisms that were described in the last episode. If you have seen that, you can find it at https://www.youtube.com/watch?v=mamop8aqFNk
=[ 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. Well 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 exend it to create a sort of fantasy console - an emulator for a machine that never existed
