func IsKeyword Uses

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.

7.6.1.2 Future Reserved Words:

const
class
enum
export
extends
import
super

7.6.1.2 Future Reserved Words (strict):

implements
interface
let
package
private
protected
public
static

func (Token) String Uses

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").
