Backbone.js & underscore.js CDN recommendation

backbone.jscdnunderscore.js

Is there any CDN sources for backbone.js and also underscore.js to use in our projects?

Best Answer

http://www.cdnjs.com hosts a lot of less popular JavaScript frameworks, including:

backbone.js: //cdnjs.cloudflare.com/ajax/libs/backbone.js/1.0.0/backbone-min.js (HTTP | HTTPS)
underscore.js: //cdnjs.cloudflare.com/ajax/libs/underscore.js/1.5.2/underscore-min.js (HTTP | HTTPS)

For convenience, here are the script tags:

Backbone.js

<script type="text/javascript"
   src="//cdnjs.cloudflare.com/ajax/libs/backbone.js/1.0.0/backbone-min.js"></script>

Underscore.js

<script
   src="//cdnjs.cloudflare.com/ajax/libs/underscore.js/1.5.2/underscore-min.js"></script>

Jquery – Best way to use Google’s hosted jQuery, but fall back to the hosted library on Google fail

You can achieve it like this:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.2.6/jquery.min.js"></script>

<script>
       window.jQuery || document.write('<script src="/path/to/your/jquery"><\/script>');
</script>

This should be in your page's <head> and any jQuery ready event handlers should be in the <body> to avoid errors (although it's not fool-proof!).

One more reason to not use Google-hosted jQuery is that in some countries, Google's domain name is banned.
