Is nodejs a front-end or back-end language?

Node.js is a JavaScript-based backend runtime environment primarily used for building server-side applications. Its main uses include: 1. Server-side development (REST API, real-time applications, web applications); 2. Creation of command line tools; 3. Development of cross-platform desktop applications. Although Node.js can also be used for front-end development, this is not its main use. Front-end development is more suitable for using JavaScript frameworks.

Node.js is a back-end language

Node.js is a runtime environment based on JavaScript. Mainly used for building server-side applications. It is not a front-end language, but a language that runs on the server, processes user requests and generates responses.

Specifically, Node.js is mainly used for:

• Server-side development: Build REST APIs, real-time applications, web applications, etc.
• Command line tools: Create scripts and utilities to automate tasks.
• Desktop Applications: Develop cross-platform desktop applications using Node.js as backend.

While Node.js can also be used for front-end development, such as building single-page applications (SPA) using JavaScript frameworks, this is not its primary use. For front-end development, it's usually better to use a JavaScript framework such as React, Angular, or Vue.js.
