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
// 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.
