Use custom meta tags to store data that you need in javascript, instead of hard-coding that data into your javascript. I store my Google Analytics code in meta tags. Here's some examples:
<meta name="google-analytics" content="1-AHFKALJ"/> <meta name="disqus" content="abcdefg"/> <meta name="uservoice" content="asdfasdf"/> <meta name="mixpanel" content="asdfasdf"/>
Company/Service Meta Tags
<meta name="microid" content="mailto+http:sha1:e6058ed7fca4a1921cq91d7f1f3b8736cd3cc1g7" />
APPLE META TAGS
<meta name="apple-mobile-web-app-capable" content="yes">
<meta content="yes" name="apple-touch-fullscreen" />
<meta name="apple-mobile-web-app-status-bar-style" content="black">
<meta name="format-detection" content="telephone=no">
<meta name="viewport" content="width = 320, initial-scale = 2.3, user-scalable = no">
