Example 1: In this example, we will see the use of ArrayBuffer.isView() using Int32Array() method.
javascript
// Creation of ArrayBuffer having a size in bytes let buffer = new ArrayBuffer(12); // Use of ArrayBuffer.isView function A = ArrayBuffer.isView(new Int32Array()) console.log(A); |
Output:
true
Note: Here output is true because Int32Array is a typed array.
Example 2: In this example, we will see the use of ArrayBuffer.isView().
javascript
// Creation of ArrayBuffer having size in bytes let buffer = new ArrayBuffer(12); // Use of ArrayBuffer.isView function A = ArrayBuffer.isView(); B = ArrayBuffer.isView(null); C = ArrayBuffer.isView(undefined); // Printing the result console.log(A); console.log(B); console.log(C); |
Output:
false false false
Note: Here output is false because the above arguments are not typed arrays.
