Allow using narrow type to match widen type.
e.g. number, 1
-> 1 | undefined
.
Default to true
.
Return value when a branch of the union T
does not match Criteria
.
Default to never
.
If you want the type to behave more like JavaScript,
you can override it to return undefined
.
Since it is a union, the result will be joined to the matched branch as union.
e.g. ElementMatch<1 | 2, 1>
-> 1 | undefined
