Have you ever wished for web apps to behave more like real apps? Well brace yourselves, a new technology called Progressive Web Apps aims to make that happen. 
On the other hand, PWAs are never packed into small offline bundles. They are entirely hosted on the server of the website. Developers update the app just like they would update a website. Therefore, all the platforms and browsers that support PWAs can use the same app. One of the biggest advantages of PWAs is code stability. The same version of the app is used for both desktop and mobile versions. PWAs can also be listed in mobile app stores for quick discovery and installation. But, on the backend, the app store will simply point to the PWAs server. In native apps, Java is used for Android and Swift for iOS. So some are concerned about the performance of PWAs because it mainly uses JavaScript code. But, performance wise, it is safe to say that Progressive Apps are getting pretty close. Some of the websites using PWAs are Forbes, Flipkart Lite, Alibaba, The Weather Channel, The Washington Post, Fandango, Jumia Travel, Lancôme, Ola, Twitter Lite, Virgin America, JioCinema, OLX, Wego, Flipboard, Telegram, Pinterest, BookMyShow, and Trivago.Numbers depict that, a value of 100 is the peak popularity for the term, 50 means that the term is half as popular and score of 0 means there was not enough data for this term. The following reasons will convince you why Progressive Web Apps will dominate in the future. This means even if you create an app, it will take a lot of work to attract users to download it. But, an average user will at least manage to visit 50 websites in a month. So, by creating progressive web apps, you can cover more users. React is managed, supported and used by Facebook. With billions of people using it daily, we can rest assured that the framework is rigorously tested.
