## Notes
- In browser environments, the implementation uses the [`performance.now`][performance-now] API. If the [`performance-now`][performance-now] API is unavailable, the implementation falls back to the [`Date`][date] object.
- In non-browser environments, the implementation uses [`process.hrtime`][process-hrtime].

## Examples
<!-- eslint no-undef: "error" -->
```javascript
var tic = require( '@stdlib/time/tic' );

function onTimeout() {

console.log( 'Elapsed: %d seconds and %d nanoseconds', elapsed[0], elapsed[1] );
