/**

* Creates an uninitialized array having a specified length.

*

* ## 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.

*

* @param length - array length

* @param dtype - data type (default: 'float64')

* @returns empty array

*

* @example

* var arr = empty( 2 );

* // returns <Float64Array>

*

* @example

* var arr = empty( 2, 'float32' );

* // returns <Float32Array>
