Return a high-resolution time difference.
npm install @stdlib/time-tocWe believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js. The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases. When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there. To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!

> Return a high-resolution time difference.
``bash`
npm install @stdlib/time-toc
`javascript`
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].
`javascript`
var delta = toc( [ 100, 123456789 ] );
// returns [
Similar to time, the returned array has format [seconds, nanoseconds].
- This function is intended to be used in conjunction with [tic][@stdlib/time/tic] for measuring performance between intervals.
`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] );
}
`

This package is part of [stdlib][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.
