Eg:
function A(){} function B(){} B.prototype = new A(); How can I check if the class B inherits class A?

By calling the super() method in the constructor method, we call the parent's constructor method and gets access to the parent's properties and methods. Inheritance is useful for code reusability: reuse properties and methods of an existing class when you create a new class.
When it comes to inheritance, JavaScript only has one construct: objects. Each object has a private property which holds a link to another object called its prototype. That prototype object has a prototype of its own, and so on until an object is reached with null as its prototype.
Try the following:
ChildClass.prototype instanceof ParentClass If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
