Command-line arguments

Gets the command-line arguments passed to a Node.js script.

• Use process.argv to get an array of all command-line arguments.
• Use Array.prototype.slice() to remove the first two elements (path of the Node.js executable and the file being executed).

const getCmdArgs = () => process.argv.slice(2);

// node my-script.js --name=John --age=30
getCmdArgs(); // ['--name=John', '--age=30']
