#Top 7 reasons you need to learn reactive programming The U s. Bureau of Labor Statistics projects a 22 percent growth in programming jobs in by 2020. Steve jobs said, in the now infamous##Lost Interview, ###Everybody in this country should learn how to program a computer, because it teaches you how to think.####We all know that learning to code is one of the most hyped skills right now and for good reason, considering the insatiable demand for developers. The U s. Bureau of Labor Statistics projects a 22 percent growth in programming jobs in by 2020. Programming##Micro Colleges##have sprung up in over#40 cities with Davinci Coders in Boulder, Colorado rated##top value##with its beginner-based, 11-week, full-immersion program for $6, 000. In May, Hubspot#made headlines#by offering $30, 000 for anyone who could help them hire a software developer. And now the newest trend reactive programming is rocking the developer community exciting tech giants like Netflix and inspiring a whole new crop of innovative startups. What is reactive programming? Spreadsheet cell formulas are hands-down the best example of reactive programming. Cells#react#to changes in the data they reference automatically. For example, A b c means that no matter what happens to B and C a will change accordingly. Don t you wish you could program anything the same way, without worrying about dependencies? Whether you re a software developer, a manager, or an architect, you need to get savvy about how reactive programming concepts are going to radically transform the industry. Consider these seven reasons: 1. Declarative vs. procedural It all comes down to the difference between an imperative system and a reactive one.##You already know how#traditional procedural programming#(imperative) works. A business user has need a and creates a spec for the programmer. The programmer figures out how to best create a system to produce the desired result and then constantly updates it as things change. Whereas a declarative system (reactive) asks the business user to simply describe what they want. Then using that description the system delivers the desired end result, of course with the help of the programmer. The focus is on what the system should do and not#how#to do it. 2. Get to market ten times faster When implemented correctly, reactive programming lets computers take care of dependency management rather than leaving that work to the programmers. As a result, the code size reduces drastically. That means 500 lines of old-school coding shrinks to five lines using reactive programming. 3. Keep up with changes In our hyper-competitive environment, the old model of waiting months to accommodate changes just doesn t work. Reactive programming means changes can be made without worrying about logic ordering. Ordering is the main cost-component of traditional programming, requiring significant analysis for each change. Just like the simplest spreadsheet, reactive programming means logic is ordered automatically based on dependencies 4. Improve code quality Traditional code is error prone. It must not only be correct; it must be called. Reactive logic is applied automatically to all changes it s the next level up in reuse beyond object-oriented programming. 5. The big kids are into it Microsoft#led the effort#by releasing Rx extensions to its. NET framework. Since then, companies like Facebook, Netflix, and Twitter have followed suit, adopting the model to slash their development time. And now Gartner has included reactive programming in its#newest report#on the hottest application developmenttrends of 2013.6. It s not just for the front end While Microsoft laid the foundation with the release of reactive extensions to. NET called Rxjs now many implementations including Flapjax, Bacon JS, and Elm are gaining popularity for front-end development. Today, startups are even starting to apply these concepts to development of the backend, which means delivering the backend part of the app in a fraction of the usual time. 7. Links business and IT Imagine IT teams and business users being able to look at the same document and discuss how to build the systems. That s how simple it is. Think of it like an executable cocktail napkin, where business users describe what they want and that specification is close enough to what IT uses to simply execute. Reactive programming opens up a whole new era of communication and collaboration between IT and business users. When implemented correctly, reactive programming is the ultimate nirvana. Those 500 lines of code are distilled away, maintenance almost disappears, and developers are empowered to operate at unprecedented speed. It s still in its infancy and I m sure we ll see some very cool implementations in 2014 as it picks up steam. Considering the#explosive demand for developers#with the latest and greatest coding toolkit, this is one trend you should jump on now.
