Function valueIt

valueIt<T, TValue>(source, valueOf): PushIterable<TValue>
Creates a push iterable with the values of elements of the source iterable.

Element value is the result of provided function call, except false, null, and undefined which are filtered out.

This can be used as a more effective mapIt / filterIt combination.
Type Parameters
- T
  
  A type of source elements.
- TValue = T
  
  A type of source element values.
Parameters
- source: Iterable<T>
  
  A source iterable.
- valueOf: ((this, element) => undefined | null | false | TValue)
  
  A function that values elements, taking the source element as the only parameter, and returning either its value, or false/null/undefined to filter it out.
  - - (this, element): undefined | null | false | TValue
    - Parameters
      
      this: void
      
      element: T
      
      Returns undefined | null | false | TValue
Returns PushIterable<TValue>
New push iterable with the element values.
