Node.js is an open source server-side JavaScript runtime environment for building scalable and maintainable high-concurrency applications.

Main uses:

• Web applications: Node.js is a popular choice for building dynamic, responsive web applications.
• Backend Services: Node.js can be used to create backend services that handle logic and data storage to power mobile applications and websites.
• Real-time applications: Node.js is ideal for building real-time applications, such as chat applications and game servers, because its asynchronous and non-blocking nature can handle a large number of concurrent connections.
• Data stream processing: Node.js has excellent data stream processing capabilities, making it ideal for processing large amounts of data, such as log analysis and sensor data processing.
• Microservices: Due to its lightweight and modularity, Node.js is ideal for building microservices, which are small, independently deployable, reusable components.

Main features:

• Asynchronous and non-blocking: Node.js adopts an asynchronous and non-blocking programming model, allowing The application continues processing other tasks while waiting for I/O operations (such as network requests or database queries) to complete.
• Single-threaded event loop: Node.js runs on a single thread and has an event loop, which can handle multiple concurrent operations at the same time, improving application performance.
• Modularity: Node.js uses a modular architecture that allows developers to create and reuse pluggable code components.
• Extensive ecosystem: Node.js has a large number of open source libraries and modules covering various functions such as database connections, authentication and web frameworks.
