- JLang Lexer:Simple lexer made using aaditmshah's lex library with some extra analysis on top
- JLang Parser: A pratt parser based on Douglas Crockford's TDOP article
- JLang Interpreter: Simple interpreter made to understand the parsed tree.
func test param {
this.id = 0;
ret this;
}
var testObj = test();
i = testObj.id;
