 The button can be made available to users via a quick action powered by the `jsButtonQuickAction` component. The actual JavaScript should be entered into a `JS_Button__mdt` custom metadata record, into the `Script__c` field with the same name as the name of the SObject. The repo contains a couple of samples for Account and Contact. The corollary is that, out of the box, only one button per SObjecttype may be supported.

 This is the fun part. The syntax is quite permissive, with some restrictions, which I will cover below. I haven't, obviously, explored all possible scenarios and the information may still be incomplete. Please raise an issue if you come across something I haven't covered.

 * Note how the syntax is linear for SOQL and DML. Coupled with JavaScript's support for manipulating arrays, this makes it easier to manipulate data, even compared to Apex in several instances.
 * SOQL and DML statements must be enclosed in `||`. Semi-colon can be inside or outside the `||`

 ### Known Limitations
 
+* Support for delete has been intentionally withheld.
 * Single-line comments are not supported. 
 * Haven't tested DML with date, datetime, boolean, geolocation and other compound fields. I will update this section as I do so.
 * Explicit use of async/await, Promises and Generators is not supported, atm.
 * DML on Files, Attachments, Documents, etc. is not supported
