Generator in Python?  What is Generator? It is a special iterative statement that is used to create your own iterator statement similar to loop, it will work step by step using next(), which means it will display the first statements, after the next statement under any method block. the generator will generate all internal content of function using next() and it uses yield() to call back the process. While is a yield? The yield will return the control from the method and not finish the complete execution but the return keyword will return the control from the method and terminate the execution. Now I am defining one simple example to understand generator. def fun():     print(10)     yield     #return 1     print(20)     yield #caling x=fun() next(x) next(x) here next() will call generator object and yield will return to control from method and again next() will call and regenerate value from function next block.

 JavaScript OOP Tutorial Overview JavaScript supports Object-Oriented Programming (OOP) principles through its prototype-based architecture. This tutorial will cover key concepts such as classes, objects, data abstraction, data encapsulation, polymorphism, and inheritance, providing step-by-step examples for each. Four Pillars of Object-Oriented Programming OOP languages adhere to four primary principles: Encapsulation : Combining data and methods within objects to ensure data security. Inheritance : Allowing classes to inherit properties and methods from parent classes, promoting code reuse and enabling method overriding. Polymorphism : Using the same function in different forms to reduce repetition and enhance code utility. Abstraction : Hiding complex implementation details to simplify usage. Is JavaScript Object-Oriented? To determine if JavaScript is object-oriented, we need to understand the difference between OOP and prototype-based programming. Object-Oriented Programming (...
