Waterfall model is a linear sequential approach, while incremental model divides the project into small increments.

• Waterfall model follows a linear and sequential approach, where each phase must be completed before moving on to the next.

• Incremental model divides the project into small increments, with each increment building upon the previous one.

• Waterfall model is less flexible to changes, as requirements are finalized early in the process.

• Incremental model allows for change...read more

Fibonacci series is a sequence of numbers where each number is the sum of the two preceding ones.

• The first two numbers of the series are always 0 and 1.

• The next number is the sum of the previous two numbers.

• The series goes on until the desired number of terms is reached.

• Example: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610, 987, 1597, 2584, 4181, 6765, 10946, 17711, 28657, 46368, 75025, 121393, 196418, 317811, 514229, 832040, 1346269, 2178309, 3524578, 5702887,...read more

The framework used in Agile methodologies is Scrum.

• Scrum is an iterative and incremental framework for managing product development.

• It emphasizes on delivering a potentially shippable product increment at the end of each sprint.

• It consists of three roles: Product Owner, Scrum Master, and Development Team.

• It has four ceremonies: Sprint Planning, Daily Scrum, Sprint Review, and Sprint Retrospective.

• It also has three artifacts: Product Backlog, Sprint Backlog, and Increment.

• Othe...read more

Yes, I know how to create wire frames.

• I have experience using tools like Balsamiq and Sketch to create wire frames.

• I understand the importance of wire frames in the design process and how they help to visualize the final product.

• I am able to work closely with designers and developers to ensure that the wire frames accurately represent the desired functionality and user experience.

Abstract class can have both abstract and non-abstract methods, while interface can only have abstract methods.

• Abstract class can have constructor, fields, and methods, while interface cannot have any implementation.

• A class can extend only one abstract class, but can implement multiple interfaces.

• Abstract class is used to define common characteristics of subclasses, while interface is used to define a contract for classes to implement.

• Example: Abstract class 'Animal' with abs...read more

Virtual DOM is a programming concept where a virtual representation of the actual DOM is created to improve performance.

• Virtual DOM is a lightweight copy of the actual DOM.

• It is used to minimize the number of changes made to the actual DOM.

• It updates only the changed elements instead of updating the entire DOM.

• React and Vue.js are popular frameworks that use Virtual DOM.

useContext API is used in React to pass data through the component tree without having to pass props down manually at every level.

• Create a context using createContext() method

• Wrap the parent component with and pass the value

• Access the context value in child components using useContext(ContextName)

Page life cycle is the sequence of events that occur during the lifespan of a web page.

• Page life cycle consists of several stages such as initialization, loading, rendering, and disposal.

• During initialization, the page and its controls are created and their properties are set.

• Loading involves retrieving and populating the controls with data.

• Rendering is the process of generating the HTML output to be sent to the client's browser.

• Disposal occurs when the page is no longer need...read more

Reducer in Redux is a pure function that takes the previous state and an action, and returns the next state.

• Reducers are used to update the state in Redux store in response to actions.

• They are pure functions, meaning they do not modify the state directly but return a new state based on the previous state and the action.

• Example: const counterReducer = (state = 0, action) => { switch(action.type) { case 'INCREMENT': return state + 1; case 'DECREMENT': return state - 1; default:...read more

Abstraction is the process of simplifying complex systems by focusing on essential details and hiding unnecessary complexities.

• Abstraction involves creating models or representations that capture the important aspects of a system while ignoring irrelevant details.

• It allows developers to work at a higher level of abstraction, making it easier to understand and manage complex systems.

• Abstraction helps in reducing complexity, improving code reusability, and enhancing maintainabi...read more

Dataflow in Redux is the unidirectional flow of data through the Redux store.

• Redux follows a strict unidirectional data flow pattern.

• Actions are dispatched to the store, which updates the state.

• The updated state is then passed down to the components for rendering.

• Components can dispatch actions to the store to update the state.

• This ensures that the state of the application is predictable and easy to reason about.
