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]. </section> <!-- /.notes --> <section class="examples"> ## Examples <!-- eslint no-undef: "error" --> ```javascript var tic = require( '@stdlib/time/tic' ); var toc = require( '@stdlib/time/toc' ); var start = tic(); setTimeout( onTimeout, 2000 ); function onTimeout() { var elapsed = toc( start ); console.log( 'Elapsed: %d seconds and %d nanoseconds', elapsed[0], elapsed[1] ); } ``` </section> <!-- /.examples --> <!-- Section for related `stdlib` packages.
