test the lexer

$ node dev/tokenize.js <<< 'let foo = "bar"'
LET let
IDENTIFIER foo
ASSIGN =
STRING "bar"

test the parser

$ node dev/ast.js <<< 'let foo = "bar";'
=============== final parse tree ===============
[ { type: 'DEC_ASSIGN',
    id: { type: 'ID', value: 'foo' },
    exp: { type: 'STRING', value: 'bar' } } ]
