Websites and applications have become an integral part of our life today.be it for shopping, watching movies, looking up on something – there is an app or website for every possible task today. One of the factors that differentiates between companies offering the same service or product is their website or app. How interactive it is, how eye-catching it is, ease of use etc all contributes to the number of customers.

JavaScript is the core technology that enables interactive web pages and is an essential part of web applications too. It has libraries which are pre-written codes that make it easier to code in terms of time-saving and memory saving. JavaScript also has frameworks like React Native which are “are collections of JavaScript code libraries that provide developers with pre-written JS code to use for routine programming features and tasks—literally a framework to build websites or web applications around.”

Talking about React Native, it is an open-source application framework created by Facebook. It is as a hybrid mobile app development framework meaning you create an app using React Native, it can be used in both IOS and Android. React Native is used in web application development too. Presently, it is used for mobile app development but since it is an open-source framework, it is being updated at a fast pace to become compatible with other platforms.

Still, React Native is very popular today.it is comparatively swift, easy and quick. Developers having expertise in JavaScript needn’t learn anything else. Apart from that, there are many reasons why React Native is so popular.

Economical: Since it provides common codebase, developers only need to create one app that can be used across different platforms. That is though one app is created, in effect multiple apps are created .this saves a lot of money that would have to spend on creating multiple apps to work on different platforms. It also earns a lot of returns.

Speedier development: React Native provides a big advantage of shorter development time. It has many ready to apply components that save time and code. Though at present the number of such packages available is less comparatively, the required code can be built up using JavaScript itself. There is no need to learn another new language for that.

Free: Since it open source software, developers can utilize the frameworks and libraries literally for free. It is MIT licensed software. Since it is under the MIT, developers have to face only limited restrictions. Also, it grants legal protection to the developers.

Modular Architecture: Modular programming is a technique of breaking down the functionality into more manageable blocks called modules. It has a lot of advantages. It helps developers to check out each others program easily and helps in easier generation of updates i.e. it increases flexibility. This feature in React Native helps in easier and quicker up-gradation and updation of applications.

Top Companies are using it: Though it is relatively a new tool, it has gained the attention of some large tech giants like Tesla, Skype, Pinterest etc. It shows how far React Native has come and how it is growing still. It provides smooth animations, platform-specific UI design and is faster. It also allows the release of application across different platforms at the same time .it allows the same front end to be used for IOS and Android and also allows sharing of business logic with web applications.

Active Growing Community: It is said that React Native framework actually started as a hackathon effort. After Facebook developed it, it has been accepted by a large number of developers worldwide. There is an organisation of dedicated open-source software enthusiasts working towards making it better day by day.

Even with all such advantages, there are still some challenges that React Native face today. Every software or tool has its pros and cons. It depends on the required functionality and features of the application needed which decides the tool to be chosen for its development.
