Applying the Liskov Substitution Principle in React
A look at the SOLID principles in action

SOLID is a set of principles that are used as guidelines for creating a clean and maintainable application that is also less buggy and error-prone.
Today, we will take a deep dive into the third principle of SOLID: the Liskov Substitution Principle. We will try to understand how this principle can help us to create a better and cleaner React application.

What Is the Liskov Substitution Principle?
In simple terms, this principle says:
“Subclasses should be substitutable for their superclasses.”
That means subclasses of a particular class should be able to replace the superclass without breaking any functionality.
Example
If PlasticDuck
is a subclass of Duck
, then we should be able to replace instances of Duck
with PlasticDuck
without any surprises.
