This chapter is focused on introducing and using client-side enhancements available with Microsoft Dynamics CRM 2016. We will cover some client-side script functions with examples and then also discuss the WEB API in the later part, which is a new way of querying CRM data directly from JavaScript.

Generally, in Microsoft Dynamics 365, JavaScript is used to perform actions in the form of scripts and ribbon commands, and in web resources.

In this chapter, we will go through the following:

• Client-side script functions with examples
• Form scripts and validating data using JavasSript
• Creating JavaScript web resources
• The Web API - a new way of querying CRM data directly from JavaScript

Now, let's look at the some scenarios for an in-depth coverage of the enhancements that can be done using JavaScript.
