The Javascript ArrayBuffer.isView() is an inbuilt function in JavaScript that is used to check whether the given argument for the function is a typed array or not.

Syntax:

ArrayBuffer.isView(p)

Parameters: It accepts a parameter either in the form of a typed array or something else. 

Return Values: It returns true if the parameter is typed array otherwise returns false. 

Example 1:  In this example, we will see the use of ArrayBuffer.isView() using Int32Array() method.

javascript




<script>
    // Creation of ArrayBuffer having a size in bytes
    var buffer = new ArrayBuffer(12);
      
    // Use of ArrayBuffer.isView function
    A = ArrayBuffer.isView(new Int32Array())
    console.log(A);
</script>

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




<script>
    // Creation of ArrayBuffer having size in bytes
    var 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);
</script>

Output: 

false
false
false

Note: Here output is false because the above arguments are not typed arrays.
