(Yet Another) Toy JSON Parser

./src/parser.ts is a toy JSON parser built in Typescript to educate myself a bit better on how lexers (tokenizers) and parsers work. I thought JSON would be easy enough as the spec is relatively small.

Please do not rely on this library. It's not fully to spec.

Use

You can see the module in action in ./src/demo.ts.

const jsonBlob = `
{
	"species": "Washingtonia filifera",
	"alternative_names": [
		"desert fan palm",
		"California fan palm"
	],
	"max_height": "66 ft"
}
`;
const parser = new Parser();

// Lex, parse, and retrieve the JS object
const parsedJSON = parser.parse(jsonBlob);
