The JavaScript Dollar Sign ($) – What’s It For?
My latest project involves some customized extensions to a WordPress based site. The designer who outsourced the development to me requested a number of JavaScript-based effects, and though I’m aready familiar with a number of other JavaScript frameworks including Sencha (formerly ExtJS), WordPress ships with jQuery and so that’s the framework that we’ve decided to use.
Ever wonder what the heck the “$” means in jQuery or why it was chosen? I sure did, and just found a great article explaining it.
