Adding Sinon to WebPack

Adding Sinon to WebPack

  • Open your project (if you're using WebPack, obviously)

  • npm install sinon --save-dev

  • You should now have Sinon in your node modules and listed in your package.json file

  • In your tests, require Sinon: var sinon = require('sinon');

Example of how JS async works for a student
class JavaScript
def initialize
@work = []
@background_worker_count = 0
end
def run(&code)
@work << code
while @work.any? || @background_worker_count > 0
instance_eval &@work.shift if @work.any?
