if..else if..else --> you used block-less else!

gistfile1.js

// If I understand JS grammar and the parsing of it correctly,
// `if .. else if ..` is a case of using else without { }, as
// it's treated almost the same as `if .. else { if .. }`.
//
// Those two have *slightly* different parse trees, but the
// nesting is clear that `if` statements only have one
// consequent and one alternate, so `else if ..` has to be treated
// as `else { if ..`.
//
// Bottom line? If you use `else if`, you're basically committing
// the "sin" of curly-brace-less `if`, the same "sin" everyone
// complained about with the iOS/OSX #gotofail.


// So.. this code:
if (foo) {
	// ..
}
else if (bar) {
	// ..
}
else if (bam) {
	// ..
}
else {
	// ..
}


// ..is actually treated as:


if (foo) {
	// ..
}
else {
	if (bar) {
		// ..
	}
	else {
		if (bam) {
			// ..
		}
		else {
			// ..
		}
	}
}
