Basic aptitude questions were asked of easy level.
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
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.
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.
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
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.
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 ...
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.

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.

Throws is used for checked exceptions in Java, while throw is used to explicitly throw an exception.
Throws is used in method signature to declare that the method may throw a checked exception.
Throw is used to actually throw an exception in the code.
Example: public void method() throws IOException { //code }
Example: throw new IOException();
Inheritance allows a class to inherit properties and behaviors from another class. Abstract classes cannot be instantiated and can have abstract methods. Interfaces define a contract for classes to implement.
