Function skipPathNil

Skips values which contains null or undefined for the given property path. Narrows the type of each property in the path from T | null | undefined to T.

Example:

const x: Observable<{ a: { b: number | null | undefined} }>;

const z: Observable<{ a: { b: number } }> = x.pipe(
  skipPathNil('a', 'b')
);
Copy

value { a: { b: 1 } } will pass through

value { a: null } will be skipped

value { a: { b: undefined } } will be skipped

With a path of just one property it does the same as skipPropertyNil.

Overloaded with up to 5 properties building the path to check.
