## Session (extensions only)

A `Session` contains information about the user currently running the script. There is only ever
one session when a user runs a script. It can be accessed via the `session` global variable.

```js
console.log(`The name of the current user is ${session.currentUser.name}.`);
```

```js
// Display the profile picture of the current user
console.log(`![${session.currentUser.name}](${session.currentUser.profilePicUrl})`);
```
