Native promises vs Bluebird promises in NODE.JS

In this article the main point is in comparing of two ways to work with an asynchronous code in Node.js. Because Node.js is native asynchronous this problem is very important. In high load applications which are built on Node.js server every second is important. So, very long time there are many discussions between different programmers: what we should to use? Going through every version of Node.js we will compare and calculate which way has more advantages in speed. All results will be displayed in understandable graphics and tables.
