ServiceNow and JavaScript

[chuymendez]

Hello Everyone!
I am currently enrolled in the SysAdmin path but I am also wondering, how much JavaScript must one know in order to use it with ServiceNow ?

@chuymendez ServiceNow has taken various low code/no code initiatives in form of Flow designer, App Engine Studio, Catalog Builder, Table builder etc. If you are in role of a System Administrator, you would barely need scripting as most of the day to day job can be easily accomplished by various configuration available on the platform.

However, if you are planning to implement some complex use cases. javascript would be needed to create client scripts, business rules and script includes. Learning Javascript is fairly easy and one can easily learning from w3schools.com.

Hope this helps.
