ArrayBuffer.isView() 静态方法判断传入值是否是 ArrayBuffer 视图之一，例如类型化数组对象或 DataView。

// Create an ArrayBuffer with a size in bytes
const buffer = new ArrayBuffer(16);

// Expected output: true

ArrayBuffer.isView(value)

如果给定参数是 ArrayBuffer 视图之一则返回 true；否则返回 false。

ArrayBuffer.isView(); // false

ArrayBuffer.isView({}); // false

ArrayBuffer.isView(undefined); // false
ArrayBuffer.isView(new ArrayBuffer(10)); // false

ArrayBuffer.isView(new Uint8Array()); // true
ArrayBuffer.isView(new Float32Array()); // true
ArrayBuffer.isView(new Int8Array(10).subarray(0, 3)); // true

const buffer = new ArrayBuffer(2);
const dv = new DataView(buffer);
ArrayBuffer.isView(dv); // true
