Module iterable/filter

filter

• filter<T, R>(predicate: (t: T) => t is R, iterable: Iterable<T>): Iterable<R>
• filter<T>(predicate: (t: T) => boolean, iterable: Iterable<T>): Iterable<T>
• filter<T, R>(predicate: (t: T) => t is R): (iterable: Iterable<T>) => Iterable<R>
• filter<T>(predicate: (t: T) => boolean): (iterable: Iterable<T>) => Iterable<T>

• Takes a predicate and a "iterable", and returns a new iterable of the same type containing the members of the given iterable which satisfy the given predicate.

  example

   filter(n => n % 2 === 0, [1, 2, 3, 4]);     //=> Iterable<[2, 4]>

        Returns t is R

  • iterable: Iterable<T>
