How to run a Javascript function at a specific time of day

some scenarios require us to run a piece of code at a specific time of day, the following method allows us to do this:

function runAtSpecificTimeOfDay(hour, minutes, func)
{
  const twentyFourHours = 86400000;
  const now = new Date();
  let eta_ms = new Date(now.getFullYear(), now.getMonth(), now.getDate(), hour, minutes, 0, 0).getTime() - now;
  if (eta_ms < 0)
 {

Shuffle Array - JavaScript ES2015, ES6
// original gist
const shuffleArray = arr => arr.sort(() => Math.random() - 0.5);
// fully random by @BetonMAN
const shuffleArray = arr => arr
.map(a => [Math.random(), a])
.sort((a, b) => a[0] - b[0])
.map(a => a[1]);
shuffleArray([1, 2, 3]) //[3, 1, 2]

Example Nginx configuration for serving pre-rendered HTML from Javascript pages/apps using the Prerender Service (https://github.com/collectiveip/prerender).Instead of using try_files (which can cause unnecessary overhead on busy servers), you could check $uri for specific file extensions and set $prerender appropriately.
# Note (November 2016):
# This config is rather outdated and left here for historical reasons, please refer to prerender.io for the latest setup information
# Serving static html to Googlebot is now considered bad practice as you should be using the escaped fragment crawling protocol

JS: A simple search function designed for filtering large lists of strings.
/**
* Demo: http://vpalos.com/sandbox/filter.js/
*
* A generic search algorithm designed for filtering (very) large lists of strings; when an input string
* contains all the parts (words or characters; whitespace is ignored) of the query, spread-out over the text
* then the string is considered to be a match. It works with the way internet browsers (e.g. Firefox, Google
* Chrome) filter address-bar suggestions on user input. It is also quite fast; on my i7 laptop, filtering
* 1) a list of ~23000 items takes around 50ms (yes, milliseconds!);
* 2) a list of ~1 million text items took under 1 second.
* It works both in NodeJS as well as in browser environments (so far I only tested FF and GC).
