3. Call the propertyIsEnumerable function on an object to check if a specific property on that object is enumerable or not. The function takes two arguments:

• obj: The object whose property you want to check.
• prop: The name of the property you want to check.

Here is an example of how to use the propertyIsEnumerable function:

index.tsx
const myObj = {
  name: 'John',
  age: 30,
};

console.log(Object.prototype.propertyIsEnumerable.call(myObj, 'name')); // Output: true
console.log(Object.prototype.propertyIsEnumerable.call(myObj, 'toString')); // Output: false

In this example, we define an object myObj with two properties: name and age. We then call the propertyIsEnumerable function on myObj to check if the name property is enumerable or not. The function returns true, which means that the name property is enumerable. We then call the function again to check if the toString property is enumerable or not. The function returns false, which means that the toString property is not enumerable.
