tic

Return a high-resolution time.

Installation

npm install @stdlib/time-tic

Usage

var tic = require( '@stdlib/time-tic' );

tic()

Returns a high-resolution time.

var t = tic();
// returns [<number>,<number>]

The returned array has the following format: [seconds, nanoseconds].

Notes

• In browser environments, the implementation uses the performance.now API. If the performance-now API is unavailable, the implementation falls back to the Date object.
• In non-browser environments, the implementation uses process.hrtime.

Examples

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] );
}
