Function forEach

  • forEach<T>(collection, iteratee?): T[]

  • Iterates over elements of collection invoking iteratee for each element. The iteratee is invoked with three arguments: (value, index|key, collection). Iteratee functions may exit iteration early by explicitly returning false.

    Note: As with other "Collections" methods, objects with a "length" property are iterated like arrays. To avoid this behavior _.forIn or _.forOwn may be used for object iteration.

    Type Parameters

    • T

    Parameters

    • collection: T[]

      The collection to iterate over.

    • Optionaliteratee: ArrayIterator<T, any>

      The function invoked per iteration.

    Returns T[]
