  • Q1. How to handle state in functional components.
  • Ans. 

    State in functional components can be managed using the useState hook in React.

    • State variables should be immutable, so always use the setter function to update them.

    • Event loop is a mechanism that allows JavaScript to perform non-blocking operations.

Interview Preparation Tips

Interview preparation tips for other job seekers - Don't really worry about success or failure. It is all about how much you learn. I have failed in at least 15-20 interviews (tbh, I stopped counting at a point, because it doesn't matter) over a span of one year before landing my dream job. I started from not knowing anything about React JS to be fluent enough for interviews. Face as many interviews you can. After the interview, note down all the questions you were asked and study on those topics. For react I divided my topics in three category. REACT(Virtual DOM, class vs functions, lifecycle methods and hooks, work flow on a button click, ROUTER, Context, HOC), REDUX(create store, apply middleware, combine reducers, pure functions, redux saga/thunk, also folder structure for redux ), REACT-REDUX(connect(), mapstatetoprops, mapdispatchtoprops, useselector and usedispatch). These are a few areas I focused on, and they all are VERY important. Study, Give Interviews, Learn, Repeat.

  • Q1. Wall the topics rite a code using of OOPS
  • Ans. 

    Object-oriented programming (OOP) is a programming paradigm based on the concept of objects, which can contain data and code.

    • Create classes to represent real-world entities

    • Encapsulate data and behavior within classes

    • Use inheritance to create relationships between classes

    • Implement polymorphism to allow objects to be treated as instances of their parent class

  • Answered by AI
  • Q2. Polymorphism code using all the properties
  • Ans. 

    Polymorphism allows objects of different classes to be treated as objects of a common superclass.

    • Polymorphism is achieved through method overriding in subclasses.

    • It allows for more flexibility and reusability in code.

    • Example: Animal superclass with subclasses Dog and Cat, both overriding the makeSound() method.

  • Answered by AI
  • Q3. Inheritance and its types
  • Ans. 

    Inheritance is a mechanism in object-oriented programming where a class inherits properties and behaviors from another class.

    • Types of inheritance include single inheritance, where a class inherits from only one parent class

    • Multiple inheritance, where a class inherits from multiple parent classes (not supported in some languages)

    • Multilevel inheritance, where a class inherits from a class that itself inherits from anothe...
