How can I check the current number of active tasks?

You can check the current number of active tasks using the `activeCount` property of the limit function.

According to the TypeScript definitions [index.d.ts:L2-L4], `activeCount` is a read-only property that returns "The number of promises that are currently running."

Here's how you'd use it:

```js
import pLimit from 'p-limit';

const limit = pLimit(5);

// Check active tasks
console.log(limit.activeCount); // Number of currently running promises
```

A practical example from the recipes shows monitoring progress with `activeCount` [recipes.md:L191-L214]:

```js
const progressInterval = setInterval(() => {
	console.log(`Running: ${limit.activeCount}, pending: ${limit.pendingCount}`);
}, 250);
```

This allows you to track how many tasks are currently executing in real-time while your queue is processing.
