For, well, pretty much ever, I've worked on the assumption that in this
structure:
function myFunc(tVar:String) {
}
the variable tVar was automatically defined in local scope: that is, I can
write
function myFunc(tVar:String) {
if (tVar == undefined) { tVar = "limpet" }
}
But you know what? That's not true! I've just discovered (and bear in mind,
I've been using that code structure for years) that I have to declare the
variable:
function myFunc(tVar:String) {
if (tVar == undefined) {var tVar:String = "limpet" }
}
That seems really weird to me. Am I wrong? Is there some other explanation?
