- Q2. Error boundary and how to handle
- Ans.
Error boundary is a React component that catches JavaScript errors anywhere in a component tree and logs those errors.
Error boundaries are React components that catch JavaScript errors in their child component tree.
They are used to prevent the entire UI from crashing due to a single error.
Error boundaries work like a JavaScript catch {} block, but for components.
They are defined using componentDidCatch lifecycle method
- Q3. Event.bind and event.property
- Q4. Use of never in typescript
- Ans.
The 'never' type in TypeScript represents a value that will never occur.
Used to indicate that a function will not return a value

- Q10. Explain map filter and reduce functions
- Ans.
Map, filter, and reduce are higher-order functions in JavaScript used to manipulate arrays.
Map: Transforms each element in an array and returns a new array with the transformed elements.
Example: [1, 2, 3].map(num => num * 2) returns [2, 4, 6].
Filter: Returns a new array with elements that pass a certain condition.
Example: [1, 2, 3].filter(num => num > 1) returns [2, 3].
Reduce: Applies a function against an accumulator ...
- Q11. How you can clone an object
- Ans.
To clone an object in JavaScript, you can use the spread operator or Object.assign() method.
Use the spread operator to create a shallow copy of an object: const clonedObj = { ...originalObj };
Use Object.assign() method to create a shallow copy of an object: const clonedObj = Object.assign({}, originalObj);
For deep cloning, you can use libraries like Lodash or write a custom function to recursively clone nested objects.
- Q12. What are the three stages of event propagation and how to handle it
- Ans.
Event propagation consists of three stages: capturing, target, and bubbling.
Capturing phase: Events are captured from the outermost element to the target element.
Target phase: Event reaches the target element where the event originated.
Bubbling phase: Events bubble up from the target element to the outermost element.
- Q13. How to handle errors in your react application
- Ans.
Errors in a React application can be handled by using error boundaries, try-catch blocks, and displaying error messages to users.
Use error boundaries to catch errors in components and display a fallback UI
Wrap code that may throw errors in try-catch blocks to handle exceptions
Use libraries like React Error Boundary to easily implement error handling
Display error messages to users to inform them about the issue and poss

Arrow functions are a concise way to write functions in JavaScript.
Arrow functions do not have their own 'this' keyword.
Arrow functions are more concise than traditional function expressions.
Arrow functions do not have their own 'arguments' object.
Arrow functions are best suited for non-method functions.
Example: const add = (a, b) => a + b;
- Q3. What is lazy loading
- Ans.
Lazy loading is a technique used in web development to defer loading non-essential resources until they are needed.
Lazy loading helps improve page load times by only loading resources when they are required.
It is commonly used for images, videos, and other media files on websites.
Lazy loading can be implemented using libraries like React.lazy() in React.js.

This process helps in optimizing performance by reducing direct ma...
- Q2. What is reconciliation in react?
- Ans.
Reconciliation in React is the process of updating the DOM to match the virtual DOM.
Reconciliation is the algorithm that React uses to update the UI efficiently.
It compares the virtual DOM with the previous virtual DOM and only updates the necessary components.
Reconciliation helps in improving performance by minimizing DOM manipulations.
Key prop is important for reconciliation to identify which items have changed, adde...
- Q3. What are closures?
- Ans.
Closures are functions that have access to variables from their outer scope even after the outer function has finished executing.
Closures allow functions to access variables from their parent function's scope
They maintain a reference to the variables they need, even after the parent function has finished executing
Closures are commonly used in event handlers and callbacks
- Q4. What is hoisting?
- Ans.
Hoisting is a JavaScript mechanism where variable and function declarations are moved to the top of their containing scope during compilation.
Hoisting applies to both variable and function declarations.
Variable declarations are hoisted to the top of their scope but not their assignments.
Function declarations are fully hoisted, meaning they can be called before they are declared.
- Q5. What are es6 features ? and code output
- Ans.
ES6 features are modern JavaScript syntax enhancements that make code more concise and readable.
Arrow functions for more concise syntax: const add = (a, b) => a + b;
Let and const for block-scoped variables: let x = 5; const y = 10;
Template literals for string interpolation: const name = 'Alice'; console.log(`Hello, ${name}!`);
Destructuring assignment for easily extracting values from objects or arrays: const { firstNam...
- Q6. What is react fiber?
- Ans.
React Fiber is a complete rewrite of React's core algorithm for rendering UI components.
React Fiber is a reimplementation of the React core algorithm.
It allows for incremental rendering, prioritizing updates based on their priority level.
Fiber reconciles the virtual DOM tree in a more efficient and flexible way.
It enables features like error boundaries, async rendering, and more.
Fiber was introduced in React version 16
- Q7. How do you implement dark mode in an application?
- Ans.
Implementing dark mode in an application involves changing the color scheme to darker tones for better visibility in low light environments.
