How do javascript programs work?

Question

JavaScript

How javascript programs work (how they work in a browser is not of interest). Excites that as how programs written on javascript are executed. I read in some sources that they are written using the node.js platform, but at the same time they use the v8 interpreter from Google. The final question is: is it possible to write desktop applications using only javascript and the v8 interpreter. And if possible, how to do it and what libraries should be connected for the GUI.

Answer 1

Under node.js is called nw.js. The instructions say how to assemble such applications. But they weigh from 50MB.
Under Windows, you can write HTA applications. The built-in feature of Windows, oddly enough, almost no one knows about it. You don't have to put anything. HTA - the same HTML, only it can work in the context of a computer, i.e. has access to where the browser does not have access - local files, activeX.
In both things, you can create very fancy interfaces with any JS libraries for normal web development (jquery, angular, etc.).
There is also Flex, but this is no longer JS.
