Then, you can import the isDataView function from the underscore library and use it in your TypeScript code as follows:

index.ts
import { isDataView } from 'underscore';

const view = new DataView(new ArrayBuffer(2));
console.log(isDataView(view)); // true

const array = new Uint8Array([0, 1, 2]);
console.log(isDataView(array)); // false

// You might want to add a type assertion if typescript doesn't detect DataView:
console.log(isDataView(array.buffer as unknown as DataView)); // false (needs `as unknown as DataView`)
