how to use the isdataview function from the underscore library in javascript

The _.isDataView() function from the Underscore library is used to check whether a given value is a DataView object or not. To use this function, you need to ensure that Underscore is included in your project.

Here is an example code snippet that demonstrates the usage of _.isDataView() function:

index.tsx
const _ = require('underscore');

const buffer = new ArrayBuffer(16);
const view = new DataView(buffer);

console.log(_.isDataView(buffer)); // false
console.log(_.isDataView(view)); // true
191 chars
8 lines

In this example, we are creating a new ArrayBuffer and a DataView object. Then, we are using the _.isDataView() function to check whether each of these objects is a DataView object or not. Finally, we are printing the results to the console.

In this case, the output will be:

index.tsx
false
true
11 chars
3 lines

since buffer is not a DataView object but view is.
