The Bang `!` operator takes a list of commands to run. So if you don't want
to run a command, pass an empty list.

[elm-discuss] Re: meaning of List.filter (String.contains lowerQuery << String.toLower << .name) people

[Ambrose Laing]

Hello,

Please take a look at this:

http://stackoverflow.com/questions/27441648/what-does-the-operator-mean-in-elm

It is very well written and answers your question.  Read the part about 
*function 
composition* and if it doesn't make sense immediately, then the rest of the 
page will be helpful.

Also, for future reference you can try looking at this page:

http://package.elm-lang.org/packages/elm-lang/core/latest/

And type your search term into the search field on the right.  It can make 
you more independent, though of course we're happy to help.
