+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).
+
+```js
+const getCmdArgs = () => process.argv.slice(2);
+```
+
+```js
+// node my-script.js --name=John --age=30
+getCmdArgs(); // ['--name=John', '--age=30']
+```
