Goals

Try to implement a tiny language but full dev stack.

• JS is our C++
• no dependencies
• pico JS implementation
• it's fun and easy to follow

Stream 1

• simple lexer (tokenazier)
• context aware errors for lexer

Stream 2

• simple parser (produces AST)
• context aware errors for parser

Stream 3

• just test things as they are

Stream 4

• add operator precedence

Stream 5

• add suport for both division and regexps
• add suport for comments

Stream 6

• remove logging 🤦‍♂️
• do some refactoring
• implement AST evaluator
• context aware errors for evaluator
• implement some simple exception logic

Stream 7

• primitive type checking

Stream 8

• finish the refactoring
• add some syntax highlighting

Stream 9

• extend lexer and parser with conditionals etc

Later

• implement functions and then closures
• macroses
• maybe switch lexing mode from "expression" to "operator"
• syntax highlight the error messages
• bytecode emission and execution
• implement some more complex exception propagation
• babel-like transformations and code emition
• VSCode language server
• try bison in JS
• emit WASM friendly output
• try true exceptions
• maybe something like source code rewrite as in prettier
