  • Returns elements from an iterable sequence as long as a specified condition is true.

    Type Parameters

    • T

      The type of the elements in the source sequence.

    • S

      The result of the predicate that is truthy/falsy.

    Parameters

    • predicate: ((value, index) => value is S)

      A function to test each element for a condition.
