Client script realtime Scenarios

[Madhulatha]

Hello Everyone,

I am looking to switch my current domain to ServiceNow. Could anyone please share some real-time client script scenarios so that I can practice and validate my knowledge?

Hi @Madhulatha 

What domain are you working currently. Do you want to move ServiceNow or you have basic experience in ServiceNow already.

Because if you are new to ServiceNow , Client script is not the first topic you should starts with.
