Can someone help me grasp the distinction between two methods of defining an optional parameter in a function:
parameter?: type
and
parameter?: type | undefined
My understanding is that the first option is essentially a shortcut for
parameter: type | undefined = undefined
Is there any nuance to the second approach?
Appreciate any insights!
If a function's parameter is optional, it defaults to undefined when not provided with any value.
So, the second statement is unnecessary for an optional parameter that accepts both 'type' and undefined.
There isn't any distinction in its functionality as long as 'type' remains strictly defined.
