Semantic tags in HTML are specific tags that provide meaning to the content they enclose.
Semantic tags help search engines and screen readers understand the structure of a webpage.
Examples of semantic tags include <header>, <footer>, <nav>, <article>, <section>, <aside>, <main>, <figure>, <figcaption>.
Using semantic tags improves SEO and accessibility of a website.
Currying is a technique in functional programming where a function with multiple arguments is transformed into a sequence of nested functions, each taking a single argument.
Currying helps in creating reusable functions and partial application.
It allows you to create new functions by fixing some parameters of an existing function.
Example: const add = (a) => (b) => a + b; add(2)(3) will return 5.
Map is used to transform each element of an array, while Filter is used to select elements based on a condition.
Map returns a new array with the same length as the original array, but with each element transformed based on a provided function.
Filter returns a new array with only the elements that pass a provided condition function.
Example for Map: [1, 2, 3].map(num => num * 2) will result in [2, 4, 6].
Example for Fi...
Map creates a new array with the results of calling a provided function on every element, while forEach executes a provided function once for each array element.
Map returns a new array with the same length as the original array, while forEach does not return anything.
Map does not mutate the original array, while forEach can mutate the original array.
Map is more suitable for transforming data and creating a new array, w...
Authentication verifies the identity of a user, while authorization determines the user's access rights.
Authentication confirms the user's identity through credentials like username and password.
Authorization determines what actions the authenticated user is allowed to perform.
Authentication precedes authorization in the security process.
Example: Logging into a website (authentication) and then accessing specific pages

Local storage data is available across all windows/tabs for that domain, while session storage data is only available wit...
I applied via Company Website and was interviewed in Oct 2024. There were 3 interview rounds.
ES6 is the latest version of ECMAScript with new features like arrow functions, classes, and template literals.
Arrow functions provide a more concise syntax for writing functions.
Classes allow for easier object-oriented programming in JavaScript.
Template literals make it easier to work with strings by allowing interpolation and multiline strings.

Coding exercise, custom hooks, UI related quetions
Hoisting is a JavaScript mechanism where variable and function declarations are moved to the top of their containing scope during compilation.
Variable declarations are hoisted 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.
CSS positions include static, relative, absolute, fixed, and sticky.
Static - default position, elements are positioned according to the normal flow of the document
Relative - positioned relative to its normal position
Absolute - positioned relative to the nearest positioned ancestor
Fixed - positioned relative to the viewport
Sticky - acts like a combination of relative and fixed positioning
Semantic tags are HTML tags that clearly define the content they contain for better accessibility and SEO.
Semantic tags provide meaning to the content they enclose, making it easier for search engines to understand the structure of the page.
Examples of semantic tags include
Using semantic tags improves the accessibility of the website for users with disabilities, as screen readers can interp
Promise chaining is a technique in JavaScript where multiple asynchronous operations are chained together to execute sequentially.
Allows for handling multiple asynchronous operations in a more readable and organized way
Each promise in the chain returns a new promise, allowing for further chaining
Helps avoid callback hell by nesting promises inside each other
Example: promise1.then(result => { return promise2; }).then(re
Virtual DOM is a lightweight copy of the actual DOM that React uses to improve performance by minimizing direct manipulation of the actual DOM.
Virtual DOM is a concept in React where a lightweight copy of the actual DOM is created and updated in memory.
When changes are made to the virtual DOM, React compares it with the actual DOM and only updates the necessary parts, reducing the number of direct manipulations to the ...
Synthetic events in React are events that are normalized by React to ensure consistent behavior across different browsers.
Synthetic events are instances of the SyntheticEvent object in React.
They are cross-browser compatible and have the same interface as native events.
They are used to handle events like onClick, onChange, etc. in React components.
Example:
Redux is a predictable state container for JavaScript apps.
Redux is a state management tool commonly used with React to manage the application's state in a predictable way.
It helps in maintaining a single source of truth for the state of the entire application.
Redux follows a unidirectional data flow, making it easier to understand how data changes over time.
Actions are dispatched to update the state in Redux, and redu...
Hooks in React are functions that let you use state and other React features without writing a class.
Hooks were introduced in React 16.8.
They allow you to use state and other React features in functional components.
Some commonly used hooks are useState, useEffect, useContext, and useReducer.
useMemo is used for memoizing values, while useCallback is used for memoizing functions.
useMemo is used to memoize a value and only recompute it when its dependencies change.
useCallback is used to memoize a function instance and only re-create it when its dependencies change.
Example: useMemo can be used to memoize the result of a complex computation, while useCallback can be used to memoize a callback function passed t

I applied via Recruitment Consulltant and was interviewed in Aug 2023. There was 1 interview round.
Type is used for defining custom data types in TypeScript, while interface is used for defining object shapes.
Type is more flexible and can be used to define unions, intersections, and primitive types.
Interface is more focused on defining the shape of an object and can be extended or implemented by other interfaces.
Type can also be used to create aliases for existing types, while interface cannot.
Example: type Person =...
Progressive web apps are web applications that provide a native app-like experience to users, with features like offline access and push notifications.
Progressive web apps use modern web capabilities to provide a user experience similar to native apps.
They are reliable, load quickly, and work offline.
They can be installed on the user's device and send push notifications.
Examples include Twitter Lite, Flipkart Lite, and

This was an easy round which went really smooth.
Calculate the Nth term in the Fibonacci sequence, where the sequence is defined as follows: F(n) = F(n-1) + F(n-2)
, with initial conditions F(1) = F(2) = 1
.
Calculate the Nth Fibonacci number efficiently using dynamic programming.
Use dynamic programming to store previously calculated Fibonacci numbers to avoid redundant calculations.
Start with base cases F(1) and F(2) as 1, then iteratively calculate F(n) using F(n-1) and F(n-2).
Ensure the input N is within the constraints 1 <= N <= 10000.
Example: For N = 5, the 5th Fibonacci number is 5 (1, 1, 2, 3, 5).
Given a positive integer N
, your task is to determine and return all prime numbers less than or equal to N
.
N = 10

A merge join in SQL is a method of combining two sorted datasets by matching corresponding rows based on a specified condition.
Merge join is used when joining two large datasets that are already sorted.
It is more efficient than other join methods like nested loop join or hash join for sorted datasets.
The join condition must be an equality condition.
Example: SELECT * FROM table1 INNER JOIN table2 ON table1.id = table2.i
