So I used the following script to exclude a DE from my journey send.
After adding in my find DE name and email field, I added it to two of my email messages in my Journey that has two messages for testing purposes.
After I ran my journey with that exclusion script in place for 2 of my messages, I have 10 contacts in my DE that I wanted to exclude and it appeared to work. I did not receive an email message to my inbox.
How would I confirm within Journey builder that this exclusion actually worked though?
