WIP interpreter for a dynamic scripting language built using Typescript to play around with lexers and parsers.
npm run test
import { Lexer } from "./lexer";
import { Parser } from "./parser";
const sourceCode = `
let hello = 2;
let test = 'sup';
`;
const lexer = new Lexer(sourceCode);
const tokens = lexer.tokenize();
const parser = new Parser(tokens);
const program = parser.parse();
for (const node of program.body) {
console.log(
`AST: ${JSON.stringify(node, null, 2)}\nSerialized output: ${
node.debug && node.debug()
}\n`
);
