/**
* Polyfill for determining whether an object is an array buffer view.
*
* ## Notes
*
* - This polyfill should only be used in environments which do not provide native `ArrayBuffer.isView` support.
* - The implementation checks whether a value is a data view or typed array.
*
* @param {*} value - value to test
* @returns {boolean} boolean indicating whether value is an array buffer view
*
* @example
* var Int8Array = require( '@stdlib/array/int8' );
* var bool = isArrayBufferView( new Int8Array( 10 ) );
* // returns true
*
* @example
* var bool = isArrayBufferView( [] );
* // returns false
