Process

1. A Tokenizer breaks up source code into a stream of tokens
2. A Parser validates to check if our tokens are syntactically valid
3. Parser converts the tokens into an AST
4. AST is interpreted with a Recursive Descent Parsing or Bytecode
5. AST is walked bottom-up, and interpreted in a wider envionment

Types

• Bytecode Interpreter
• AST Interpreter
