I see a piece of JavaScript code in my Node.js application.
( function() { console.log("gg") } )(this) I would like to know why use => ( function(){} )(this) this type of structure, and how does this compile.
I am understanding why we have this two brackets ()(), and why this code would work.

You use repeating to print repeating strings: const repeating = require('repeating'); console. log(repeating(100, 'unicorn '));
The cloneNode() method creates a copy of a node, and returns the clone. The cloneNode() method clones all attributes and their values. Set the deep parameter to true if you also want to clone descendants (children).
The Buffer. copy() method simply copies all the values from input buffer to another buffer.
This is a self invoking anonymous function. This pattern is useful when you want to hide variables from the global namespace.
(function(){ var foo = "foo"; })(); console.log(window.foo); // undefined Also see What do parentheses surrounding a JavaScript object/function/class declaration mean?
What advantages does using (function(window, document, undefined) { … })(window, document) confer?
