Syntax help

I don't understand why we can shorten:

users.forEach( username => { getProfile(username); });

To:

users.forEach(getProfile);

What is happening here that makes these syntaxes the same?

Hi Vincent

You can shorten the function because of the new arrow function syntax.

I recommend you to watch this video about arrow functions: https://teamtreehouse.com/library/-basic-arrow-syntax

I hope I helped you.
