I have an object like:
var foo = {
a: {
b: ... || ... || ... || 30
}
, c: bar(... || ... || ... || 30)
};
Is it possible to access foo.a.b
key instead of writing again ... || ... || ... || 30
in the bar
call?
I also can do:
foo.c = bar(foo.a.b);
But I would choose a shorter way if possible.
I tried to do bar(this.a.b)
that doesn't work (Cannot read property 'b' of undefined.
).
