{{alias}}( collection, initial, reducer[, thisArg] )
    Applies a function against an accumulator and each element in a collection
    and returns the accumulated result.

    When invoked, the reduction function is provided four arguments:

    - `accumulator`: accumulated value
    - `value`: collection value

    - `collection`: the input collection

    If provided an empty collection, the function returns the initial value.

    Parameters

        function.

    reducer: Function
        Function to invoke for each element in the input collection.

    thisArg: any (optional)
        Execution context.

    Returns

    out: any
        Accumulated result.

    Examples
    --------
    > function sum( acc, v ) { return acc + v; };
