sndrs / get.js
Last active May 3, 2017 13:43
tiny version of lodash.get https://lodash.com/docs#get
const get = (obj = {}, path = '', defaultValue) =>
path
.replace(/\[(.+?)\]/g, '.$1')
.split('.')
.reduce((o, key) => o[key], obj) || defaultValue;
// PERFORMANCE
// It's slower than lodash (surprise surprise), but it's about 97% smaller:

sndrs / QueueableModule-PoC.js
Last active August 29, 2015 14:24
PoC of a JS module loading + monitoring queue – trying to avoid the '9am' rush
// Modules extend a generic queueable module, and add themselves to a global
// queue, which manages running them synchronously, as soon as it can (on the next tick).
// Running order is based on 'high', 'medium' and 'low' priorities, which modules
// can assign themselves.
// The queue also measures how long modules take to run, and if a module exceeds 10ms
// the queue sends a warning (probably to sentry IRL).
// The log() calls work best with chrome devtools, rather than the repl one
// QUEUE TO HANDLE REGISTRATION AND RUNNING OF MODULES
