The following jQuery works with or without a semicolon after the function. Why?

jQuery(document).ready(function(){
jQuery("#red").treeview({
    animated: "fast",
    collapsed: true,
    control: "#treecontrol",
    persist: "cookie"
})

});

It works on all browsers. Wouldn't this cause an error?

• Why should it? Semicolons are optional (at least at this position). – Felix Kling Commented May 15, 2012 at 15:27

JavaScript doesn't actually require semicolons. That's just convention.

I remend using semicolons, just like I'd remend indenting your code.
