Function filterIt

filterIt<T, TTarget>(source, test): PushIterable<TTarget>
Creates a push iterable with all source iterable elements extending the given type.
Type Parameters
- T
  
  A type of source elements.
- TTarget
  
  Target type.
Parameters
- source: Iterable<T>
  
  A source iterable.
- test: ((this, element) => element is TTarget)
  
  A predicate function to test that element extends the type TTarget. Returns true to keep the element, orfalse otherwise. It accepts the tested element as the only parameter.
  - - (this, element): element is TTarget
    - Parameters
      
      this: void
      
      element: T
      
      Returns element is TTarget
Returns PushIterable<TTarget>
New push iterable with the elements that pass the test. If no elements passed the test, an empty iterable will be returned.

filterIt<T>(source, test): PushIterable<T>
Creates a push iterable with all source iterable elements that pass the test implemented by the provided function.
Type Parameters
- T
  
  A type of source elements.
Parameters
- source: Iterable<T>
  
  A source iterable.
- test: ((this, element) => boolean)
  
  A predicate function to test each element. Returns true to keep the element, or false otherwise. It accepts the tested element as the only parameter.
  - - (this, element): boolean
    - Parameters
      
      this: void
      
      element: T
      
      Returns boolean
Returns PushIterable<T>
New push iterable with the elements that pass the test. If no elements passed the test, an empty iterable will be returned.
