I see in the jQuery code this structure but I don't know the name and how use correctly.
(function($) {
...
})(jQuery);
I suppose it's a form of past arguments to the function.
this will execute the function immediately (immediately invoked)

I know, similar questions have been asked but none answered my question of What does the second () mean?
And also no the syntax is not (function...) rather its just function(a,d){...}(Jquery,...);
Is it that we are making objects of Jquery, I am also using Hammer.js so basically the second paranthesis has (Jquery, Hammer)

I came across with a piece of code with new syntax for me, What this syntax means in js? I mean this parentheses at the beginning:
(function () {
//...
})()
It's called IIFE
basically, you can define a a function and invoke it immediately without declaring a name for it.

onSelect(option, (0, _getOptionText2.default)(option))
I saw this in one of the node modules I use and I'm pretty confused by the second argument which is wrapped by parentheses. How does that work? There is no function which it is invoking.

Could I get an explanation of the follow code snippet?
(function()
{
alert();
})();
This looks like an anonymous function and the alert() function gets executed. I don't understand the semantic meaning of the outer parentheses. What does this part of the snippet mean?
(
)()
this represents the immediately executable function. in easier way, it means that function being declared and called/executed simultaneously.
