I’ve seen $. used but I’ve never understood what it stands for. Example that got me thinking:
$.getJSON("url", function(result){
$.each(result, function(i, field){
$(".test").append(field + " ");
});
EDIT: Right, I’m embarrassed. I knew it referred to jQuery but I’ve only used jQuery for DOM manipulation, I’m so used to having elements to be worked on, it threw off guard a little. Thanks for your informative replies.
$ is an alias for jQuery – see the very top of the library for the code.
