Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.
Get started now by creating a new collection.
Is there a benefit to doing this?

In general, the backslash is used to escape the suceeding character (such as
\n
or quote characters inside a string).In this case, it allows line breaks inside a macro definition, making the code more readable.
