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.

Hi @chuymendez ,

It really depends on what you would like to work with: Developer, admin or processes. Some basic understanding of Javascript is recommended but not a requirement.

If my answer has helped with your question, please mark my answer as accepted solution and give a thumb up.

best regards

Hello @chuymendez,

Firstly it depends on your role and responsibility in your servicenow team that weather you'll be working on admin, developer or both sides. Then it also depends upon the requirement as in some cases you can achieve most complex requirements without a single line of scripting in ServiceNow or maybe in some cases you need a good amount of scripting to achieve the required functionality.

Although ServiceNow promotes the platform as low code/no code, but you need to have basic JavaScript knowledge like datatypes, functions, conditional statements, loops, etc for basic customizations too. So it's good to have it handy at beginning too.

If my answer helped your understanding then please mark my answer helpful and correct.

Thanks & Regards,

HI @chuymendez 

Greetings!!

Learning is always good , but yes it is important to know how to start and where to start. JavaScript is required in SN world but the way SN is changing to Low code / No code it is not required to have very deep knowledge.

Please follow Chuck Tomasi video to learn Java Script.
