React.js is a new open source library for building user interfaces. It has many of the great qualities of functional programming, but unlike F#, it is not purely functional.
One problem with traditional libraries like XUL and Flash is that the UI is not completely encapsulated. Each of the controls exposes some interface so that you can interact with it. These controls could be managed individually, or they could be exposed and managed through classes like UIView and UIControl.
The problems you run into will also include cross-browser compatibility, in which you’ll want to make sure that everything runs smoothly across all the different web browsers. You’ll also have to deal with the quirks of the different browsers, like the lack of support for things like XMLHttpRequest. This usually means that your users have to download the library instead of using the library directly. This means that you have to come up with a strategy for loading a fast library when necessary, and a slow library when the need is not so urgent.
The greatest benefit of this code is that the code is highly extensible. In particular, the UI controls can be implemented by other developers without having to go through the pain of writing an entirely new component.
So, what’s so great about React.js? That’s a good question. First, it is really small and easy to maintain. That alone will reduce development costs.
A great advantage of React.js is that you don’t have to think about any templating, or even about inversion of control. This means that your code will be flexible and also provide a testable system. If you have to change the UI due to changes in your program, you won’t have to worry about having to get rid of all your code and start from scratch.
Does React.js provide a declarative way of writing programs? No, but if you’re just beginning you can write your UI in terms of components. Think of them as algorithms. Component-based systems allow you to define properties that are part of the UI without knowing anything about how they work. The code is just defined by the shapes and sizes of the components.
The component-based system makes it easy to think about drawing shapes, animation, and other fanciness. While a traditional library might require you to learn about programming primitives like numbers and strings, these components are simple and easy to understand.
Another popular fact about React.js is that you can use it to create a web application from scratch. For example, many of the top mobile game engines in the world were built with React.js. All it takes is a few lines of code. This allows you to experiment with different technologies and select a system that fits your needs.
It has also been proven that it’s easy to solve a complicated problem. React.js requires a lot of boilerplate code, but the amount of code required to solve a complex problem is greatly reduced, making it an extremely valuable tool.
React.js works well with AngularJS, the latest version of the popular MVC framework. If you’re already using Angular, it should be fairly easy to upgrade your code to use React.js, without losing any functionality.
There are many benefits to developing web applications using this technology. It is also a very fast and flexible way to build applications. It doesn’t make any assumptions about your data models, but works with any code that supports HTML.
