tutorial 1: code libraries and hosting/CDN

Notes

• jQuery is a JavaScript library that is popular with developers
• streamlines syntax
• leverages capabilities of other HTML-friendly resources--CSS, AJAX, etc.
• makes animation easy
• 2 main ways to use libraries
• download and host your own copy
• link to a hosted library through a CDN
• Hosting vs. CDN
• If you host a library, you need to factor in the size of the library file
• Hosting also meangs maintaining the library as updates are made--if you don't, you may end up using depreciated code.
• Using a CDN alleviates any file size concerns
• CDNs also take care of maintenance and updates; you may have to change a line of code when major updates occur.
