{{alias}}( length[, dtype] )
    Creates an uninitialized array having a specified length.

    In browser environments, the function always returns zero-filled arrays.

    If `dtype` is 'generic', the function always returns a zero-filled array.

    In Node.js versions >=3.0.0, the underlying memory of returned typed arrays
    is *not* initialized. Memory contents are unknown and may contain
    *sensitive* data.

    The function supports the following data types:

    - float64: double-precision floating-point numbers (IEEE 754)
    - float32: single-precision floating-point numbers (IEEE 754)
    - complex128: double-precision complex floating-point numbers
    - complex64: single-precision complex floating-point numbers
    - int32: 32-bit two's complement signed integers
    - uint32: 32-bit unsigned integers
    - int16: 16-bit two's complement signed integers
    - uint16: 16-bit unsigned integers
    - int8: 8-bit two's complement signed integers
    - uint8: 8-bit unsigned integers
    - uint8c: 8-bit unsigned integers clamped to 0-255
    - generic: generic JavaScript values

    The default array data type is `float64`.

    Parameters
    ----------
    length: integer
        Array length.

    dtype: string (optional)
        Data type. Default: 'float64'.

    Returns
    -------
    out: TypedArray|Array
        Output array.

    Examples
    --------
    > var arr = {{alias}}( 2 )
    <Float64Array>
    > arr = {{alias}}( 2, 'float32' )
    <Float32Array>
