Module array/filter

filter

• filter<T>(fn: ArrPred<T>, arr: ArrayLike<T>): T[]
• filter<T>(fn: ArrPred<T>): (arr: ArrayLike<T>) => T[]

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

  example

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