Wrap curly brackets in parenthesis or no?

In the official documentation Todo example on this page:

Inside example 3.5 I see this <h1>Todo List ({{incompleteCount}})</h1> and I noticed throughout the rest of the tutorial it seems that the parenthesis are not really needed. I did not include them here and the app still works fine. Is there a reason or benefit to wrapping your double-curly brackets in parenthesis?

Thanks in advance,

The parentheses are not special syntax. This template literally displays them on the page:

Todo List (5)

Oh my goodness I’ve been focused on learning Meteor, I didn’t realize something so simple lol. It’s just actual parenthesis. I think I’ll be done for today. Thanks for your help good sir!
