Can someone help me understand what this means?

I am unfamiliar with node and js and I am not fully understanding what this bit of code is doing.var serialPort = require("serialport"); var SerialPort = serialPort.SerialPort; I understand that it is trying to initialize the Serial Port, but is there anymore detail that someone could provide? What is happening in the background of node.js?
