Two functions – one object
importance: 2
Is it possible to create functions A
and B
so that new A() == new B()
?
function
A
(
)
{
...
}
function
B
(
)
{
...
}
let
a =
new
A
(
)
;
let
b =
new
B
(
)
;
alert
(
a ==
b )
;
// true
If it is, then provide an example of their code.
Yes, it’s possible.
If a function returns an object then new
returns it instead of this
.
So they can, for instance, return the same externally defined object obj
:
let
obj =
{
}
;
function
A
(
)
{
return
obj;
}
function
B
(
)
{
return
obj;
}
alert
(
new
A
(
)
==
new
B
(
)
)
;
// true
