understanding.Roland Kuhn at the beginning of the video, introducing what to say this week: In this last week of the reactive programming course, we'll focus first on something which is implicitly there alrea Dy. Namely, that actors as independent agents of computation is by default distributed. Normally you run them just on different CPU ' s in the same system. But, there are nothing stopping the running them on different network hosts, and we'

This lesson helps your think in reactive programming by explaining why it's a beneficial paradigm for programming. See how reactive programming helps you understand the dynamic behavior of a value evolving over time.It allows specify the dynamic behavior of a value completely at the time of declaration.console.clear ();varA = 3;varb = A * 10; Console.log (b);//Then if you want to the change ' a ' and wants

What is functional reactive programmingHttp://limboy.me/ios/2013/06/19/frp-reactivecocoa.htmlFunctional reactive Programming (hereinafter referred to as FRP) is a programming paradigm that responds to change. Let's take a look at a small piece of codea = 2b = 2c = a + b // c is 4b = 3// now what is the value of c?If you use FRP, c the value will b change as the value changes, so it is called "responsive pro

associated with the width of its parent container so that it adapts to the client's screen.The CSS3 specification introduces a new unit called REM, similar to the EM class, but REM is easier to use relative to HTML elements. REM is relative to the HTML element, and don't forget to reset the HTML font size: html { font-size:100%; } When you are finished, you can define the font size of the response, as follows: @media (min-width: 640px) { body {font-siz

embedded video is also responsive (responsive).3– fontsThe final step of this tutorial is absolutely important, but often overlooked by web developers-fonts. Up to now, most developers, including myself, have used the image to define the size of the font. Although pixels are OK for normal site use, there should be a responsive font for responsive web sites. In fact, a responsive font size should be associated with the width of its parent container so that it adapts to the client's screen.The
