In this enchanting journey, we’ll explore the intricacies of JavaScript, the spells it can cast, and the realms it can conquer within the Dynamics CRM universe.

Chapter 1: The Essence of JavaScript

What is JavaScript?

JavaScript, the language of enchantment, is a client-side programming language that breathes life into web pages.

In the realm of Dynamics CRM, JavaScript is a formidable force used for processing and performing logical operations on CRM forms and data in real time.

Chapter 2: Unveiling the Magic of Form Event Programming

Form Event Programming

Form Event Programming is the art of handling client-side scenarios and behaviors within Dynamics CRM forms.

Web Resources

JavaScript finds its abode in the form of web resources in Microsoft Dynamics 365. These resources, akin to magical scrolls, are summoned during client-side events. Each dedicated function or method within these resources acts as a spell triggered by specific events, casting its magic on the CRM forms.
