Package-Level Type Names (only one)


	/* sort by:  |  */
	
		Token is the set of lexical tokens in JavaScript (ECMA5).

		
			
				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").

Package-Level Functions (total 3)


	 func IsId(tkn 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.
