Summary

In this chapter, we looked at the configuration and customization of a ServiceNow instance, and when it is appropriate to use both. We also introduced the two script types: client- and server-side scripts. This chapter also explained the running order of scripts in ServiceNow, the importance of order 1000, and how this can affect script outcomes. We introduced preparing to script, with some considerations before starting; finally, we looked at the script editor. 

In the next chapter, we will look at the ServiceNow glide class. This will show you the script ServiceNow provides you, which can be used to complement your JavaScript. The glide class is a frequently used aspect of ServiceNow scripting, and understanding its use will allow you to write helpful basic scripts and serve as a great first step into writing more advanced code.
