# How do I pass command line arguments to a Node.js program and receive them?

In Node.js, you can pass command line arguments to your script the same as you would for any other command line application. Simply type your arguments after the script path separated with a space as shown below:

```bash
node task.js foo bar
```

Then you can retrieve the arguments from the `process.argv` array like this:

```jsx
process.argv.forEach((val, index) => {
  console.log(index + ': ' + val);
});
```

The first element (index 0) is always a path to your Node.js executable and the second element (index 1) is a path to your script. Additional elements are the ones you pass when executing the script. In the case of the example above. The `process.argv` array would look something like this:

```
0: /path/to/node
1: /path/to/task.js
2: foo
3: bar
```

You can also use packages such as `commander`, `yargs` or `minimist` to help you handle and parse command line arguments.

Remember, command line arguments are string so you need to convert them to other types when necessary.
