Module boa::syntax::lexer

A lexical analyzer for JavaScript source code.

This module contains the Boa lexer or tokenizer implementation.

The Lexer splits its input source code into a sequence of input elements called tokens, represented by the Token structure. It also removes whitespace and comments and attaches them to the next token.

This is tightly coupled with the parser due to the javascript goal-symbol requirements as documented by the spec.
