  2. MEAN Stack Interview Questions in 2023 www.instaily.com

  3. Introduction The MEAN stack is a JavaScript-based technology stack for building dynamic web sites and web applications. MEAN is named after MongoDB, Express, Angular, and Node.js, the four key technologies that make up the layers of the stack. It is a popular, full-stack, and scalable JavaScript-based stack that can be used to develop a wide range of web applications. www.instaily.com

  4. Q1. What are the benefits of using the MEAN Stack? The MEAN Stack offers several benefits that make it a popular choice for web development: The MEAN Stack uses JavaScript as the single language for the entire web application The MEAN Stack consists of open-source components MEAN stack is fast and scalable. MEAN stack is flexible and versatile. The MEAN Stack supports code reusability, allowing developers to share code components across different parts of the web application To know more in details visit our blog www.instaily.com/mean-stack-interview-questions www.instaily.com

  5. Q2. What are the components of the MEAN Stack? The components of the MEAN Stack are as follows: MongoDB Node.js Express.js Angular To know more in details visit our blog www.instaily.com/mean-stack-interview-questions www.instaily.com

  6. Q3. What is Mongoose? Mongoose is an object data modeling (ODM) library used in conjunction with Node.js and MongoDB. It provides a schema-based solution to model the application’s data, offering validation, querying, and middleware capabilities.

  7. Q4. What is a routing guard in Angular? In Angular, a routing guard is a feature that allows developers to control access to specific routes in the application. Routing guards are used to protect routes from unauthorized access and perform actions before navigating to a particular route.

  8. Q5. What is data modeling? Data modeling is the process of defining the structure of data in a database, including relationships between different data entities. In the context of the MEAN Stack, data modeling involves designing the schema for MongoDB collections.

  9. Q6. What is callback hell? Callback hell, also known as the pyramid of doom, is a term used to describe the situation when multiple nested callbacks are used in asynchronous JavaScript code. In such scenarios, handling asynchronous tasks can lead to deeply nested and indented code, making it challenging to read, understand, and maintain.

  10. Q7. What is the difference between Node.js and JavaScript? Node.js and JavaScript are both related to the JavaScript language, but they serve different purposes. JavaScript is a scripting language primarily used in web browsers to create interactive and dynamic user interfaces. On the other hand, Node.js is a server-side runtime environment that allows developers to execute JavaScript code on the server.

  11. Q8. What are the different ways to deploy a MEAN stack application? MEAN stack applications can be deployed using various methods, depending on the requirements and infrastructure. Some common deployment approaches are as follows: Deploying on a cloud platform Using containerization Deploying on a traditional server To know more in details visit our blog www.instaily.com/mean-stack-interview-questions www.instaily.com

  12. Q9. What are the challenges of MEAN stack development? MEAN stack development comes with its own set of challenges. Some challenges include: Handling asynchronous programming and avoiding callback hell by using modern JavaScript features like Promises or Async/Await. Addressing security vulnerabilities and implementing proper data validation to prevent potential attacks. Dealing with complex data modeling and managing relationships between entities in MongoDB.
