This introductory example demonstrates
instanceof in action, checking if
myCar is an instance of the
Car class. Now, let's buckle up and explore the depths of
instanceof operator allows you to verify this relationship between an object and its prototype.
instanceof are used for type checking, they serve different purposes. The
typeof operator returns a string indicating the type of the unevaluated operand. It's great for primitive data types like
boolean. On the other hand,
instanceof checks the prototype chain of an object, making it more suitable for custom objects and complex data types.
Here's how you can distinguish them:
In the above example,
typeof correctly identifies
num as a number, but
instanceof returns false because
num is not an instance of the
dateInstance is an instance of the
instanceof operator or simply check its type:
Both checks confirm that
dateInstance is indeed an object.
instanceof with Custom Objects
Let's create a custom object and see
instanceof at work:
dog is verified as an instance of the
instanceof and object-oriented programming, check out these external resources:
Remember, practice makes perfect. Experiment with
instanceof to get a feel for its behavior and quirks. Happy coding!
