XF 1.5 Where to add additional javascript?


Active member
Forgive me if this has already been asked, I did a search and got 10 pages of results that I don't have time to look through.

I created a simple Christmas style (off of the UI.X style) here https://apelounge.net/ . I uploaded my snow javascript file to my root directory and added my additional javascript code to the style's header template. My questions are: Is there a better place to add the additional javascript code? Am I going to mess up my forum by doing what I've done? Everything seems to be working fine.
