Description
Polymorphism (of subtypes) – the main distinguishing feature of modern OOP. It allows to significantly reduce the number of conditional constructs and makes the code extensible.
At the same time, polymorphism is a large and deep topic that requires serious preparation. This is where design patterns and SOLID principles come in. All this is an integral part of JavaScript development for professional developers.
