A Script is a sequence of instructions that are carried in response to an event.
An event is usually something triggered by the end-user, for example, opening a new Form or clicking on a button. Each event can have a series of Scripts attached to it.
Verj.io supports two scripting languages: JavaScript and the legacy Form Processing Language (FPL). JavaScript 
Scripts have access to the extensive Verj.io JavaScript API.
Our JavaScript API provides access to all elements on a Form, including Fields, Tables and Controls. It gives you access to the browser client and session data and provides a suite of useful services.
We recommend writing all new Scripts in JavaScript.
You can create a new Script in the Workspace by right-clicking in the Entities tree and selecting New > Script (JavaScript).
