Virtual DOM is a lightweight copy of the actual DOM, used to improve performance by minimizing actual DOM manipulation.

• Virtual DOM is a concept used in ReactJS.

• It is a lightweight copy of the actual DOM.

• It is used to improve performance by minimizing actual DOM manipulation.

• When a change is made to the actual DOM, the Virtual DOM is updated.

• The Virtual DOM then calculates the difference between the previous and updated state.

• Only the necessary changes are then made to the act...read more

The Software Development Lifecycle (SDLC) is a structured process for developing software applications through various stages.

• 1. Requirements Gathering: Identify what the software needs to do, e.g., user stories or functional specifications.

• 2. Design: Create architecture and design documents, e.g., UML diagrams or wireframes.

• 3. Implementation: Write the actual code, e.g., using languages like Java, Python, or JavaScript.

• 4. Testing: Validate the software through unit tests, in...read more

Requirement analysis is the process of identifying and documenting the needs and expectations of stakeholders for a software project.

• Gathering requirements through interviews, surveys, and workshops with stakeholders.

• Documenting functional requirements, such as user stories or use cases, to define what the system should do.

• Identifying non-functional requirements, like performance, security, and usability, to ensure the system meets quality standards.

• Prioritizing requirements ...read more

To bind events in React JS, use the 'on' prefix followed by the event name in camelCase.

• Use the 'on' prefix followed by the event name in camelCase (e.g. onClick, onSubmit)

• Pass a function as the event handler (e.g. onClick={() => console.log('Button clicked')})

• Bind 'this' to the event handler function if it uses 'this' (e.g. onClick={this.handleClick.bind(this)})

• Use arrow functions to automatically bind 'this' (e.g. onClick={() => this.handleClick()})

Class is a blueprint for creating objects with properties and methods, while functional component is a function that returns JSX.

• Class can have state and lifecycle methods, while functional component cannot.

• Functional component is simpler and easier to read and test.

• Class can be extended and reused, while functional component cannot.

• Example of class component: class MyComponent extends React.Component {}

• Example of functional component: const MyComponent = () => { return

JavaScript data types refer to the different types of values that can be stored and manipulated in JavaScript.

• JavaScript has several data types including string, number, boolean, object, function, and undefined.

• Examples: 'hello' (string), 42 (number), true (boolean), { key: 'value' } (object), function() { } (function), undefined.

• Data types can be dynamically assigned in JavaScript, meaning a variable can change its type during runtime.

Implementing CRUD operations using Spring Boot and JPA connection

• Create Entity class with @Entity annotation

• Create Repository interface extending JpaRepository

• Use @RestController and @Autowired for Controller class

• Implement methods for Create, Read, Update, Delete operations

JS Event Loop is the mechanism that allows JavaScript to perform non-blocking operations by handling asynchronous tasks.

• Event Loop is responsible for executing code, collecting and processing events, and executing queued sub-tasks.

• It consists of a Call Stack, Web APIs, Callback Queue, and Microtask Queue.

• Example: setTimeout() function in JavaScript uses the Event Loop to schedule a function to run after a specified time.

Hooks are functions that allow you to use state and other React features in functional components. useMemo() is a hook that memoizes a function's result.

• Hooks are used in functional components to access state and lifecycle methods

• useMemo() is used to memoize a function's result to improve performance

• Example: const [count, setCount] = useState(0);

• Example: const memoizedValue = useMemo(() => computeExpensiveValue(a, b), [a, b]);

Arrow functions are a shorthand syntax for writing functions in JavaScript.

• Arrow functions have a concise syntax and do not bind their own 'this' keyword.

• They are commonly used in functional programming and with array methods like map, filter, and reduce.

• Arrow functions cannot be used as constructors and do not have a prototype property.

• They are also not suitable for methods that require the 'this' keyword to be bound to the object calling the method.

Angular is a popular front-end framework for building dynamic web applications.

• Developed and maintained by Google

• Uses TypeScript for building applications

• Follows the component-based architecture

• Supports two-way data binding

• Has a powerful CLI for scaffolding projects

• Link is used in HTML to connect external CSS files, while import is used in JavaScript to bring in modules or components.

• Link is a HTML tag, while import is a JavaScript statement.

• Link is used for styling and layout, while import is used for code organization and modularity.

• Example: for link, import React from 'react'; for import.

TMG event refers to a type of event in the Windows operating system that is related to the Threat Management Gateway.

• TMG events are generated by the Microsoft Forefront Threat Management Gateway (TMG) to provide information about network activity and security events.

• Examples of TMG events include firewall rule violations, denial of service attacks, and malware detection.

• TMG events can be monitored and analyzed to improve network security and troubleshoot issues.
