Editor's Notes
- #8: That’s what Apex is – how do we code it? It is possible to use a third party IDE like Sublime or Eclipse – but you can also code right in your browser. Our Developer Console allows you to create and edit code, debug your applications and run unit tests. POTENTIAL DEMO: Show Anonymous Apex in the Dev Console
- #11: Functions: https://www.salesforce.com/us/developer/docs/pages/Content/pages_variables_functions.htm
- #13: It uses the Schedulable interface, which allows us define the execute method to control what logic will be run on the schedule
