JavaScript plus sign in front of function name 3 answers

That is so that the function declaration is a function expression, so that it can be executed immediately.

Usually that is done by putting parentheses around it:

(function ($) { "use strict";
//...
}(window.jQuery));

or:

(function ($) { "use strict";
//...
})(window.jQuery);
