18
```javascript
19
import { now } from "lodash-es";
20

21
// Get current timestamp
22
const timestamp = now(); // 1640995200000 (example)
23

24
// Useful for performance measurement
25
const start = now();
26
// ... some operation
27
const duration = now() - start;
28
console.log(`Operation took ${duration}ms`);

30
// Alternative to Date.now()
31
console.log(now() === Date.now()); // true (approximately)
