Classes in TypeScript serve as blueprints for creating objects. They encapsulate data (properties) and behavior (methods) related to a specific entity. Classes help in organizing code by defining the structure and behavior of objects. Objects, also known as instances, are created from classes. ...
If you're familiar with Spring, you know that both of those objects need to be cast to the correct object types when they are retrieved from the application context file. Again, this is how I do class casting in Scala, but there is another (preferred) way to do this ... I might wr...
