Mixed Bag of Tips, Tricks & Resources - Part 1
The ServiceNow developer community has a vast combined knowledge with lots of developers who are willing to share what they’ve learned (and more joining the ranks every day). Over the years, I have benefited from their blog posts, YouTubes, and various other content.
Every once in a while, I stumble across information that catches my attention, information I think might come in very handy someday.
So, I’m sharing a collection of some of them here:
