Could you clarify what you mean by "GD"? In many contexts, GD stands for **Group Discussion**, often used in recruitment or academic settings. If that's what you're referring to, here are some common details about Group Discussions (GD):

### Purpose:
- **Evaluate communication skills**: The GD is typically used to assess how well you express your thoughts and articulate them in a group.
- **Teamwork and leadership**: It's a good way to see how you collaborate with others, share ideas, and potentially lead the conversation.
- **Problem-solving ability**: In many cases, a GD will focus on current affairs or hypothetical situations to evaluate how well you analyze and come up with solutions.

### Format:
- **Topic Assignment**: Participants are given a topic (usually related to current affairs, technology, business, etc.).
- **Duration**: The GD might last from 15 to 30 minutes, depending on the group size.
- **Group Size**: Typically involves 6 to 10 participants.

### Common Evaluation Criteria:
1. **Communication Skills**: Clarity, confidence, and articulation.
2. **Team Interaction**: Listening skills, respecting others’ views, and contributing effectively.
3. **Knowledge**: Awareness of the topic and the ability to make relevant points.
4. **Leadership & Initiative**: Taking charge when needed or encouraging others to participate.
5. **Problem-Solving Ability**: Offering logical, well-thought-out solutions or perspectives.

### Tips for a Successful GD:
1. **Prepare for common topics**: Stay updated on current affairs and popular business trends.
2. **Participate actively**: Speak up, but don’t dominate the discussion. Allow others to express their views as well.
3. **Stay calm and composed**: Don’t interrupt others, and be respectful.
4. **Structure your thoughts**: Try to present your points logically, with examples when possible.
5. **Be a good listener**: Acknowledge other participants' ideas and build upon them.

Is this what you were referring to, or is there a different context for "GD"? Let me know if you need further clarification!

Q1. What are custom hooks in React, and what are their use cases? Additionally, can you provide an example of a custom hook that performs an API call and utilizes the retrieved data?
Ans. 
Custom hooks in React are reusable functions that allow you to extract component logic into separate functions for better code organization and reusability.
• Custom hooks are created using the 'use' prefix and can be used to share logic between components.

• Use cases for custom hooks include fetching data from an API, handling form state, managing local storage, and more.

• Example of a custom hook for API call: const useFetc...read more

Q2. What is the difference between useMemo and useCallback in React?
Ans. 
useMemo is used to memoize a value, while useCallback is used to memoize a function.
• useMemo is used to memoize a value and recompute it only when its dependencies change.

• useCallback is used to memoize a callback function and prevent unnecessary re-renders.

• Example: useMemo can be used to memoize the result of a complex computation, while useCallback can be used to memoize an event handler function.

Q7. What is hoisting in JavaScript?
Ans. 
Hoisting in JavaScript is the behavior where variable and function declarations are moved to the top of their containing scope during the compilation phase.
• Variable declarations are hoisted to the top of their scope, but not their initializations.

• Function declarations are fully hoisted, meaning they can be called before they are declared.

• Hoisting can lead to unexpected behavior if not understood properly.

Q8. What is event bubbling in JavaScript?
Ans. 
Event bubbling is the propagation of events from the target element up through its ancestors in the DOM tree.
• Events triggered on a child element will 'bubble up' and trigger on parent elements.

• Event listeners can be attached to parent elements to handle events from multiple child elements.

• Stopping event propagation can be done using event.stopPropagation() or event.stopImmediatePropagation().

• Deep copy creates a new object and also creates new copies of all nested objects.

• Shallow copy can be achieved using Object.assign() or spread operator, while deep copy can be achieved using JSON.parse(

Q13. What will be the output of the following JavaScript code fragment: `const a; function test() { console.log(a); }; test();`?
Ans. 
The code will throw an error because 'a' is declared but not initialized.
• The code will result in a ReferenceError because 'a' is declared but not assigned a value.

• Variables declared with 'const' must be initialized at the time of declaration.

• Initializing 'a' with a value before calling test() will prevent the error.
