Lesson 24 / 30
The process Object
Read command-line arguments and runtime details with process.argv, process.cwd and process.platform.
Command-line arguments
process.argv is an array — the first two entries are the node binary and script path, the rest are your arguments.
// greet.js
const name = process.argv[2] || "stranger";
console.log(`Hello, ${name}!`);
// $ node greet.js Ada
// Hello, Ada!cwd & platform
Useful runtime details without any import.
console.log(process.cwd()); // current working directory
console.log(process.platform); // 'linux', 'darwin', 'win32'
console.log(process.version); // v20.11.0
