Function validIdentifier

identifier.go:51–66

validIdentifier checks to see if a string is a valid JavaScript identifier E.g: justLettersAndNumbers1 -> true a key with spaces -> false 1startsWithANumber -> false

(s string)

//     a key with spaces      -> false
//     1startsWithANumber	  -> false
func validIdentifier(s string) bool {
	if reservedWords[s] || s == "" {
		return false
	}

	for i, r := range s {
		if i == 0 && !validFirstRune(r) {
			return false
		}
		if i != 0 && !validSecondaryRune(r) {
			return false
		}
	}

	return true
}

// validFirstRune returns true for runes that are valid
// as the first rune in an identifier.
