I believe it's perfectly valid to write blocks (for no particular
reason) without any keyword.
I.e.:
function foo() {
var x = 42;
{
var y = 10;
print(x+y);
}
return x;
}
Obviously it's useless, but it is valid.
You could add a label to the block if you want to actually use it for something:
bar: {
if (x == 10) { y = 10; break bar; }
if (x == 20) { y = 0; break bar; }
...
}
