Are you a Developer? Do you write JavaScript code? Did you recently hear about the SharePoint Framework and you’re intrigued and you’re looking to learn more? Are you looking for somewhere to work on your code without necessarily having to consume resources from your Production tenant that you’re running Office 365 within?
Consider heading over to http://dev.office.com and setting up a development tenant. The tenant is limited to a small number of user licenses and is meant to allow you to develop in an environment where you don’t have to be worried about anything happening to your production environment.
Give it a try… and then head over to http://dev.office.com/sharepoint
