Function skipPropertyUndefined

skipPropertyUndefined<T, P extends string | number | symbol>(
    prop: P,
): (
    source: Observable<T>,
) => Observable<
    {
        [X in string
        | number
        | symbol]: X extends P ? NonUndefined<T[X]> : T[X]
    },
>
Skips / filters values which contains undefined for the given property. Narrows the type of the given property within the object type from T | undefined to just T.

Example:
```
const x: Observable<{ a: number, b: string | undefined }>;

const z: Observable<{ a: number, b: string }> = x.pipe(
  skipPropertyUndefined('b')
);
```
value { a: 1, b: 'foo' } will pass through

value { a: 1, b: undefined } will be skipped
Type Parameters
- T
- P extends string | number | symbol
Parameters
- prop: P
  name of the property to check
Returns (
    source: Observable<T>,
) => Observable<
    {
        [X in string
        | number
        | symbol]: X extends P ? NonUndefined<T[X]> : T[X]
