Function filter

filter<T, S>(pred: TypeGuardPredicate<T, S>): (src: Iterable<T>) => Iterable<S>
Filters items from a source iterable using a predicate, optionally narrowing the element type.
Type Parameters
- T
  Element type produced by the source iterable.
- S
  Narrowed element type when pred acts as a type guard.
Parameters
- pred: TypeGuardPredicate<T, S>
  Predicate invoked with each element and its index to determine inclusion.
Returns (src: Iterable<T>) => Iterable<S>
A transformer that yields every element for which pred returns a truthy value.
Throws
Error Rethrows any error thrown by pred.
Example
```
const odds = [
  ...pipeInto(
    [1, 2, 3, 4],
    filter((value) => value % 2 === 1)
  ),
];
console.log(odds); // [1, 3]
```
