@stdlib/time-toc NPM

Installation

npm install @stdlib/time-toc

Usage

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

toc( time )

Returns a high-resolution time difference, where time is a two-element array with format [seconds, nanoseconds].

var delta = toc( [ 100, 123456789 ] );
// returns [<number>,<number>]

Similar to time, the returned array has format [seconds, nanoseconds].

Notes

This function is intended to be used in conjunction with tic for measuring performance between intervals.

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] );
}

Notice

This package is part of stdlib, a standard library for JavaScript and Node.js, with an emphasis on numerical and scientific computing. The library provides a collection of robust, high performance libraries for mathematics, statistics, streams, utilities, and more.
