Dropbox vs React

You can use Dropbox via website, by installing a desktop client that creates a folder that you simply drag and drop files into, or with their mobile app. Everything synchronizes across all devices used and cloud storage. And Dropbox offers easy methods of sharing whatever is within it.

Dropbox is available on iOS, Android, BlackBerry, Windows, OS X and Linux. By having a client for so many OS's pretty much anyone is covered no matter what kind of device or OS they are using.

Using a desktop client: right click on the folder you want to share and select Dropbox > Share This Folder, then enter the e-mail addressees of people you want to share the folder with.

If a small portion of the file is changed it sends/receives only the differences (not the whole file), which is fast and bandwidth-efficient.

Whether using desktop client or web interface, simply right click on the file you want to share and select Dropbox > Share link, then send the link to the people you want to share the file with. The recipient does not require a Dropbox account.

Dropbox personal accounts start out free, with 2GB of space, but users can get extra space by recommending the site to friends, or taking part in events like "Dropquest", where users can win extra space by solving puzzles.

Dropbox offers native Linux support, integrates with Nautilus file manager.

As long as you have enough storage available, you can upload files of any size using Dropbox desktop client.

To save bandwidth and download speed you can choose to compress a folder into a zip archive for download.

To not slow down the network or save traffic you can limit the upload and download speeds of Dropbox.

There are official and third-party Dropbox add-ons that extend the functionality of the service and add ease of use of existing features.

Additionally, Dropbox can be integrated with existing applications to bring its functionality to other apps.

Dropbox keeps deleted and earlier versions of files for a month.

Your files always synced online means instant disaster recovery. When your hard drive becomes unbootable, pick up another laptop and just carry on with your life from where you last saved.

You get extra free space for you and your friend if they sign up.

Since every single UI component is created independently in JavaScript, it becomes very easy to reuse them throughout your app without having to re-write them.

React is built by Facebook engineers initially to be used only for their inner projects especially to solve the problem of building large complex applications with constantly changing data.

React can render it's components and data server side, then it sends those components as HTML to the browser.

This ensures faster initial loading time and SEO friendliness out of the box, since it's indexed as any other static website by search engines.

Instead of relying on the DOM, React implements a virtual DOM from scratch, allowing it to calculate precisely what needs to be patched during the next screen refresh. This is orders of magnitude faster than fiddling with the DOM itself.

React's one-way data binding (or one-way data flow) means that it's easy to see where and how your UI is updated and where you need to make changes. It's also very easy to keep everything modular, fast and well-organized.

ReactJS can be used independently as the only library for building the front-end, or it can be used alongside JavaScript libraries such as jQuery, or even Angular.

React provides a template engine (JSX) which is easy to use. But it's not mandatory.

The framework is widely used in the industry.

Since React's virtual DOM system is implemented completely in JavaScript, it's very easy to write UI test cases.

React has an official Chrome Extension which is used as a developing and debugging tool. It can be used to quickly and painlessly debug your application or view the whole application structure as it's rendered.

Flux is a platform agnostic pattern which can technically be used with any application or programming language.

One of Flux' main features is that it enforces uni-directional data flow which means that views do not change the data directly.

With React this is useful because this way it's easier to understand an application as it starts getting more complicated. By having two-way data binding, lead to unpredictable changes, where changing one model's data would end up updating another model. By using the Flux architecture, this can be avoided.

Since React v0.15, SVG is fully supported. React supports all SVG attributes that are recognized by today's browsers.

React is just a view library, so you still have (almost) full control over how your app behaves.

Reagent, Om, Rum, etc.

React is used on one of the most visited websites on the planet, Facebook. With stellar results and with millions of people experiencing it every day.
