Angular And Node Js Interview Questions
Angular and Node.js Interview Questions
Angular And Node Js Interview Questions
Angular and Node.js are essential technologies for modern web and mobile app development. Interviews involving these frameworks often focus on core concepts, such as Angular's component-based architecture and data binding, and Node.js's event-driven, non-blocking I/O model. Questions also explore practical aspects like dependency management, testing, and performance optimization. By understanding these technologies, candidates demonstrate their ability to create scalable, efficient, and user-friendly applications.

1 - Angular: What is the difference between a component and a directive?
A component is a reusable UI element with its own logic and template, while a directive modifies the behaviour or appearance of an existing element.
2) Angular: What is dependency injection?
Dependency injection is a design pattern that allows components to receive dependencies from external sources, making it easier to test and maintain code.
3) Angular: What is the difference between a service and a factory?
A service is a singleton object that is instantiated once and shared across the application, while a factory returns a new instance of an object each time it is invoked.
4) Node.js: What is event driven programming?
Event driven programming is a programming paradigm where the flow of the program is controlled by events, such as user input or network requests.
5) Node.js: What is a callback function?
A callback function is a function that is passed as an argument to another function, which calls the callback function when an event occurs.
6) Node.js: What is the difference between a synchronous and asynchronous function?
A synchronous function executes code sequentially, blocking the event loop, while an asynchronous function executes code concurrently, allowing the event loop to continue processing other tasks.
7) Node.js: What is the purpose of a middleware?
A middleware is a function that provides additional functionality between the request and response lifecycle of an HTTP request.
8) Node.js: What are RESTful APIs?
RESTful APIs are web services that follow the representational state transfer (REST) architectural style, which defines how data is represented and transferred between clients and servers.
9) Node.js: What is Express.js?
Express.js is a popular Node.js framework for building web applications and RESTful APIs.
10) Node.js: What is MongoDB?
MongoDB is a popular NoSQL database that stores data in a JSON like document format.
11 - Node.js: What is the purpose of a database schema?
A database schema defines the structure and relationships between data stored in a database.
12) Node.js: What is a transaction?
A transaction is a unit of work that represents a change to the database. It ensures that the changes are made consistently and atomically, or not at all.
13) Angular: What is the ngModel directive used for?
The ngModel directive binds an Angular component's property to a form control, allowing users to interact with the form using the component.
14) Angular: What is a dependency injector?
A dependency injector is a service responsible for creating and managing dependencies for Angular components and services.
15) Angular: What is the purpose of the ngFor directive?
The ngFor directive is used to iterate over an array or collection of items, creating a new instance of a template for each item.
