type Token int
Token is the set of lexical tokens in JavaScript (ECMA5).
func IsKeyword
func IsKeyword(literal string) (Token, bool)
IsKeyword returns the keyword token if literal is a keyword, a KEYWORD token if the literal is a future keyword (const, let, class, super, ...), or 0 if the literal is not a keyword.
If the literal is a keyword, IsKeyword returns a second value indicating if the literal is considered a future keyword in strict-mode only.

func (Token) String
func (tkn Token) String() string
String returns the string corresponding to the token. For operators, delimiters, and keywords the string is the actual token string (e.g., for the token PLUS, the String() is "+"). For all other tokens the string corresponds to the token name (e.g. for the token IDENTIFIER, the string is "IDENTIFIER").
