You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: token.go
    path of file: ./repos/go-starter-kit/vendor/github.com/dop251/goja/token
    
    the code of the file until where you have to start completion: // Package token defines constants representing the lexical tokens of JavaScript (ECMA5).
package token

import (
	"strconv"
)

// Token is the set of lexical tokens in JavaScript (ECMA5).
type Token int

// 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 "I
