It's useful like this.
isCheckoutMode = $("cart").hasClass("checkout");
$("calculator").enable("checkout", isCheckoutMode);
$("catalog").enable("searching", !isCheckoutMode);
Without enable(), the code would need to look like this:
isCheckoutMode = $("cart").hasClass("checkout");
if (isCheckoutMode) {
$("calculator").addClass("checkout");
$("catalog").removeClass("searching");
} else {
$("calculator").removeClass("checkout");
$("catalog").addClass("searching");
}
It's not a toggle, because even if the class is currently applied, it
doesn't mean you will want to remove it. You are only enabling it
conditionally on some boolean value which may change dynamically as
the code is run.
