How does process.versions work?

process.versions is a property of the process global object in Node.js, which contains the version numbers of Node.js and its dependencies. This property is an object that includes the version numbers of the following components: node: the version number of the Node.js runtime. v8: the version number of the V8 JavaScript engine that is bundled with Node.js. uv: the version number of the libuv library, which provides the asynchronous I/O and event handling capabilities of Node.js. zlib: the version number of the zlib compression library that is used by Node.js. brotli: the version number of the Brotli compression library that is used by Node.js. ares: the version number of the c-ares library, which provides asynchronous DNS resolution capabilities to Node.js. modules: the version number of the ESM (ECMAScript modules) implementation in Node.js. nghttp2: the version number of the nghttp2 library, which provides HTTP/2 support to Node.js. napi: the version number of the Node-API (N-API) interface, which provides a stable, ABI-stable C/C++ API for developing Node.js native addons. Developers can access these version numbers by reading the appropriate properties of the process.versions object. For example, to get the version number of Node.js, developers can use process.versions.node. Overall, process.versions provides a convenient way for developers to check the version numbers of Node.js and its dependencies, which can be useful when troubleshooting issues or ensuring compatibility with specific versions of these components.

console.log(`Node.js version: ${process.versions.node}`);
console.log(`V8 version: ${process.versions.v8}`);
console.log(`libuv version: ${process.versions.uv}`);
console.log(`zlib version: ${process.versions.zlib}`);
console.log(`brotli version: ${process.versions.brotli}`);
console.log(`c-ares version: ${process.versions.ares}`);
console.log(`ESM version: ${process.versions.modules}`);
console.log(`nghttp2 version: ${process.versions.nghttp2}`);
console.log(`N-API version: ${process.versions.napi}`);

In this example, we use console.log to print the version numbers of Node.js and its dependencies to the console. We access these version numbers by reading the appropriate properties of the process.versions object. When this code runs, it will print the version numbers of Node.js and its dependencies to the console. For example: yaml Copy code
