I'm trying to customize the Gallery block using the new Gutenberk Block API thing.
Long story short, I need to add a filter to do the customization.
So what is the purpose of the namespace argument when calling the
addFilter function? I am failing to find an explanation for the purpose of this argument.
Edit: Essentially, I am trying to do what is shown in this post/question. Still, the question remains, what is the purpose of the namespace argument, and its role in the scope of the project?
Also, if you're going to downvote, can you explain why?
