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...
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.

Various state management techniques in React include Context API, Redux, and local state.
Context API: React's built-in solution for passing data through the component tree without having to pass props down manually at every level.
Redux: A popular state management library for React applications, allowing for a centralized store to manage application state.
Local state: Managing state within individual components using us
Redux is a predictable state container for JavaScript apps. Middlewares are functions that intercept actions before they reach the reducer.
Redux follows a unidirectional data flow architecture.
Middlewares in Redux are functions that can intercept, modify, or dispatch actions.
Common use cases for middlewares include logging, asynchronous API calls, and handling side effects.
Examples of popular Redux middlewares are Redu...
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.
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().
Block scope and function scope are two types of scopes in JavaScript that determine the visibility and accessibility of variables.
Block scope refers to the visibility of variables within a block of code enclosed by curly braces. Variables declared with 'let' and 'const' have block scope.
Function scope refers to the visibility of variables within a function. Variables declared with 'var' have function scope.
Variables de...
Yes, I have experience working with semantic tags in HTML.
Used semantic tags like <header>, <nav>, <main>, <section>, <article>, <aside>, <footer> for better structure and SEO.
Understand the importance of using semantic tags for accessibility and search engine optimization.
Semantic tags help in organizing content and making it more readable for developers and browsers.
Various methods for creating an object in JavaScript include object literals, constructor functions, ES6 classes, and Object.create() method.
Object literals: var obj = { key: value };
Constructor functions: function ObjectName() { this.key = value; } var obj = new ObjectName();
ES6 classes: class ClassName { constructor() { this.key = value; } } var obj = new ClassName();
Object.create() method: var obj = Object.create(pr
Shallow copy only copies the references of nested objects, while deep copy creates new copies of nested objects.
Shallow copy creates a new object but does not create copies of nested objects, only copies their references.
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(
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.
CSS can be used to arrange elements in a row and column layout using flexbox or grid layout properties.
Use display: flex; for a row layout and display: flex; flex-direction: column; for a column layout
Use justify-content and align-items properties to align items in the main axis and cross axis respectively
For grid layout, use display: grid; and grid-template-columns or grid-template-rows to define the layout
Yes, I have utilized CSS preprocessors such as SASS and LESS.
I have experience using SASS to streamline my CSS workflow by utilizing variables, mixins, and nesting.
I have also worked with LESS to improve code organization and maintainability through features like variables and functions.

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 persists even after the browser is closed, while session storage is cleared when the browser is closed.

Local storage stores data with no limit, while session storage has a limit of around 5MB.
Local storage data is available across all windows/tabs for that domain, while session storage data is only available wit...
Challenges in automation include dynamic UI elements, data synchronization, and maintenance of test scripts.
Dynamic UI elements can be challenging to automate as they may change frequently.
Data synchronization between different systems can be difficult to achieve in automation.
Maintenance of test scripts can be time-consuming, especially when application changes frequently.
To read data and assert with db value in API automation, use API response to extract data and compare with database query result.
Extract data from API response using JSON parsing libraries like Gson or Jackson
Execute database query to retrieve expected value
Compare the extracted data with the database value using assertion libraries like TestNG or JUnit
