Array Methods in JavaScript: Filter, Map, Reduce
var data = ['apple', 'pear', 'orange', 'orange', 'apple', 'lime', 'lime'];
data
.filter((item, index, array) => item !== 'pear') /* Let's filter out all pears (as they are horrible!) */
.reduce((total, item, index, array) => {
if (total.indexOf(item) === -1) total.push(item); // Only add unique items to the array (de-duplication)
return total; // Return the cumulative total
}, [] /* Initial value, can be any primitive e.g. [], boolean etc */)
.map((item, index, array) => item + ' juice') /* Add the word 'juice' to the end */
.forEach((item, index, array) => item + ' ' + index) /* Add an index */

Configuring a SOCKS proxy server in Chrome
From: http://www.chromium.org/developers/design-documents/network-stack/socks-proxy
To configure chrome to proxy traffic through the SOCKS v5 proxy server myproxy:8080, launch chrome with these two command-line flags:
--proxy-server="socks5://myproxy:8080"
--host-resolver-rules="MAP * 0.0.0.0 , EXCLUDE myproxy"
The first thing to check when debugging is look at the Proxy tab on about:net-internals, and verify what the effective proxy settings are:
chrome://net-internals/#proxy
