SOLID Principle in Programming: Understand With Real Life Examples, Microservice Architecture - Introduction, Challeneges & Best Practices. The difference between yield and return is that return terminates the function but yield only pauses the execution of the function and returns the value against it each time. The process of deriving a new class from an old class (parent class) is known as inheritance. Classes. Same name, but different contents and roles. The parent class is the one from which the properties are inherited, and the child class is the one inheriting the properties.
