Node.js Programming Language
Node.js is an open-source, cross-platform, back-end JavaScript runtime environment that runs on the V8 engine and executes JavaScript code outside a web browser.
#What is Node.js?
Node.js is a runtime environment built on Chrome’s V8 JavaScript engine that allows developers to run JavaScript code outside of a web browser. It is an open-source, cross-platform, and event-driven JavaScript runtime. Node.js has become popular for building server-side applications, particularly for web development.
#Node.js Key Features
Most-recognizable Node.js features include:
- Asynchronous and non-blocking I/O operations
- Lightweight and efficient
- Built-in package manager (npm)
- Cross-platform support
- Large and active open-source community
- Scalable and high-performance
#Node.js Use-Cases
Some of the Node.js use-cases are:
- Server-side web applications
- Real-time applications (chat, gaming, etc.)
- Command-line tools and scripts
- Microservices
- Internet of Things (IoT)
- Machine learning and artificial intelligence
#Node.js Pros
