Function filter

filter<T, S>(predicate, thisArg?): OperatorFunction<T, S>
Filters the elements of an iterable sequence based on a predicate.
Type Parameters
- T
- S
Parameters
- predicate: ((value, index) => value is S)
  
  A function to test each source element for a condition.
  - - (value, index): value is S
    - Parameters
      
      value: T
      
      index: number
      
      Returns value is S
- Optional thisArg: any
  
  Optional this for binding.
Returns OperatorFunction<T, S>
An operator which returns an iterable sequence that contains elements from the input sequence that satisfy the condition.
