In JavaScript's if-then-else there is technically no elseif branch.
But it works if you write it this way:
if (condition) {
} else if (other_condition) {
} else {
}
To make it obvious what is really happening you can expand the above code using an additional pair of { and }:
if (condition) {
} else {
if (other_condition) {
} else {
}
}
In the first example we're using some implicit JS behavior about {} uses. We can omit these curly braces if there is only one statement inside. Which is the case in this construct, because the inner if-then-else only counts as one statment. The truth is that those are 2 nested if-statements. And not an if-statement with 2 branches, as it may appear on first sight.
This way it resembles the elseif that is present in other languages.
It is a question of style and preference which way you use it.
