Static methods can be called without creating an instance of the class
Static blocks are used to initialize static variables
Static keyword can also be used to create nested classes

Loops are used to execute a set of instructions repeatedly. There are three types: for, while, and do-while.
For loop: executes a set of statements a fixed number of times
While loop: executes a set of statements as long as the condition is true
Do-while loop: executes a set of statements at least once, then repeats as long as the condition is true

- Q1. Rate yourself in js, node js, react, MongoDB (separately)
- Q2. Typeof null, typeof undefined, typeof {}, typeof NaN
- Q3. What changes came in es6
- Ans.
ES6 introduced several new features and improvements to JavaScript, making it more powerful and efficient.
Arrow functions for more concise syntax
Let and const for block-scoped variables
Classes for easier object-oriented programming
Template literals for easier string interpolation
Default parameters and rest parameters for function arguments
Destructuring assignment for easier data extraction
Promises for asynchronous prog
- Q4. This keyword, closures, hoisting
- Q5. Are let and cont variables hoisted?
- Ans.
Yes, let and const variables are hoisted but not initialized.
let and const variables are hoisted to the top of their block scope, but they are not initialized until the actual line of code is executed.
This means that you cannot access a let or const variable before it is declared in the code.
For example, trying to access a let variable before it is declared will result in a ReferenceError.
- Q6. What is global context
- Ans.
Global context refers to the overall environment or setting in which something exists or operates.
Global context encompasses all variables, functions, and objects that are accessible throughout an entire program.
It can be thought of as the 'big picture' view of a program's execution.
In web development, global context includes the window object in JavaScript.
- Q7. What is temporal deadzone
- Ans.
Temporal dead zone is a period during the variable creation process where accessing the variable results in a ReferenceError.
Occurs when trying to access a variable before it has been declared with let or const
Happens due to the variable being in the temporal dead zone until it is declared
Example: accessing a variable before its declaration will result in a ReferenceError
- Q8. What is modules? types of modules in nodejs
- Ans.
Modules in Node.js are reusable blocks of code that encapsulate related functionality.
Modules in Node.js can be built-in modules like fs (file system) or third-party modules like express.
Modules help in organizing code into separate files for better maintainability and reusability.
Modules can be imported using the require() function in Node.js.
- Q9. Index in mongodb, why we need index, is index good or bad?
- Ans.
Indexes in MongoDB improve query performance by allowing the database to quickly locate and retrieve specific documents.
Indexes help to speed up query performance by allowing the database to quickly locate specific documents based on the indexed fields.
Without indexes, MongoDB would have to perform a collection scan, which can be slow and resource-intensive.
Indexes can be created on single fields or compound fields to ...
- Q10. What are hooks , use of useRef
- Ans.
Hooks are a feature in React that allow you to use state and other React features in functional components. useRef is a hook that allows you to create a mutable object that persists for the lifetime of the component.
Hooks are used to add state and lifecycle methods to functional components in React
useRef is used to create a mutable reference that persists between renders
useRef can be used to access DOM elements directl
- Q11. Fs module, http module, worker thread?
- Q12. Why we use mongoose not mongodb driver?
- Ans.
Mongoose is an Object Data Modeling (ODM) library for MongoDB that provides a higher level of abstraction and simplifies interactions with the database.
Mongoose provides schema validation which helps maintain data integrity.
Mongoose simplifies querying and data manipulation with built-in functions.
Mongoose supports middleware functions for pre and post processing of data operations.

- Q1. What's does the useCallback and usememo in react ?
- Ans.
useCallback and useMemo are hooks in React used for performance optimization.
useCallback is used to memoize a function and prevent unnecessary re-renders.
useMemo is used to memoize a value and prevent unnecessary re-computations.
Both hooks are used to optimize performance by reducing unnecessary re-renders and re-computations.
useCallback is useful when passing down functions to child components.

- Q2. What's difference between async await and promise ?
- Ans.
Async/await is a syntactic sugar over Promises in JavaScript.
Async/await makes asynchronous code look and behave like synchronous code.
Promises are objects that represent the eventual completion or failure of an asynchronous operation.
Async/await is easier to read and write than Promises.
Async/await can only be used in functions that are marked as async.
Promises can be used anywhere in the code.

- Q1. What is the difference between classes and struct
- Ans.
Classes are reference types while structs are value types.
Classes support inheritance while structs do not.
Classes have default access modifier as internal while structs have it as private.
Classes have a destructor while structs do not.
Classes are allocated on heap while structs are allocated on stack.
Classes can be null while structs cannot.
- Q2. Dispatch Queue vs operations
- Ans.
Dispatch Queue is a thread-safe way to execute tasks asynchronously, while Operations are a way to encapsulate tasks.
Dispatch Queue is a high-level API for managing concurrent operations.
Operations are objects that encapsulate a single task or multiple tasks.
Dispatch Queue is simpler to use and recommended for most use cases.
Operations provide more control over task dependencies and cancellation.
Both can be used togeth
