+	* Creates an uninitialized array having the same length and data type as a provided input array.
+	*
+	* ## Notes
+	*
+	* -   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 recognizes 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
+	*
+	* @param x - input array from which to derive the output array length
+	* @param dtype - data type
