Use WebWorkers and promises to run sync heavy functions in a worker (process) and get the result in a promise
function asyncThread(fn, ...args) {
if (!window.Worker) throw Promise.reject(
new ReferenceError(`WebWorkers aren't available.`)
);
const fnWorker = `
self.onmessage = function(message) {
(${fn.toString()})
.apply(null, message.data)
.then(result => self.postMessage(result));

Rails Rspec model testing skeleton & cheat sheet using rspec-rails, shoulda-matchers, shoulda-callbacks, and factory_girl_rails. Pretty much a brain dump of examples of what you can (should?) test in a model. Pick & choose what you like, and please let me know if there are any errors or new/changed features out there.
