Asynchronous Event Driven Brain Teaser Using Node.js

Node.js has emerged as a powerful platform for building scalable and efficient backend applications. This research study provides a comprehensive overview of Node.js development, encompassing its core concepts, asynchronous programming paradigms, and essential tools. This study analyzes the fundamentals of Node.js, including event-driven architecture, asynchronous operations, and package management using npm. Database integration is explored through popular ORMs like Mongoose and Sequelize for MongoDB and MySQL, respectively and also highlights the significance of authentication and authorization using Passport.js and JWT. To ensure application quality, effective testing and debugging strategies using frameworks such as Mocha, Chai, and Jest are also reviewed. By combining these elements, developers can create robust and high-performance Node.js applications.
