Dynamics 365/CRM JavaScript Reference

Dynamics 365/CRM has come a long way since the 4.0 and 2011 days when JavaScript was the only way to meet most custom requirements. We now have business rules, roll-up fields, calculated fields, process flows and more that can be configured to meet custom requirements right within the GUI (which is the recommended path when you can get away with it). But for the times when you can’t get what you need from the front end, here’s a quick D365/CRM JavaScript reference to help with syntax in your custom form scripts:
