Progressive Web Apps are web applications with enhanced features and modern APIs. We can also say that it is a mixture of mobile apps and web apps. •        Progressive PWAs – Progressive apps are progressive because it works for every user regardless of browser. One can use these apps all around the world. Progressive web apps work well because they build with progressive enhancement. •        Fit To Screen or Responsive – Progressive web apps are responsive. The responsive app means it fits every screen size whether it is mobile, tablets, laptop, or any other device. •        No Connectivity dependency – PWAs don’t depend upon the connectivity. These apps work on services, workers, and lower networks or offline. •        Mobile Apps like Feel – Apps built in PWAs looks like mobile apps. Their navigation and other features feel like an app instead of a web app. •        High Security – These apps serve on HTTPS, so no one can access the app without proper authorization. •        Easily Discoverable – Service worker register scope allows search engines to find PWA apps easily. •        Customer Engagement – Feature of Push notification makes these apps engage with users easily. Also, PWAs can be shared via URL and no complex installation is required. Differentiate between Native Apps, Traditional Apps, and PWA Apps 1.      Native Apps – Native mobile apps are coded in programming languages like Objective C or java for the respective operating system. Features of Native apps: • Most reliable and fast performance • Device hardware’s complete access • It modifies system settings • It can use device’s features like camera, address book and many more • Updates go through the store regulations and then send to the users 2.      Traditional Apps – Features of traditional apps: • These apps build using stands like HTML, CSS, and JavaScript • Web apps delivery depends upon the speed of internet • Traditional apps have limited access to the device’s feature • Web apps depend upon the internet connectivity • Web apps can never be installed on your device 3.      PWA Apps – Features of Progressive Web Apps: • Updates are instant. • PWAs have limited access to device’s features just like traditional apps • Major disadvantage of PWAs is no IOS support yet

What Is New In Angular-9? What is new in Angular-9? Features and fixes of Angular-9.In Angular-9, all the existing bugs & drawbacks have been resolved. Angular is the most eminent open-source framework which is used for building a web as well as mobile applications. Angular is developed by Google, which includes all of the tools and components which are required for building a web application. Angular follows a clear roadmap. In this version of angular, it introduces IVY compiler. Let’s discuss this in detail. Angular version 9 applications use IVY compiler and runtime by default. Ivy solves long-standard problems. Ivy is an internal and renders pipeline of Angular. It renders the engine and takes input into a component of angular with a template and then translates into instruction that changes the DOM (Document Object Model). Ivy compiler is the replacing and hidden away view engine that doesn’t change the way of work in Angular. These changes don’t have an impact on the code that’s being generated.  IVY compiler has many additional advantages: Apart From this, VE- View Engine, is responsible for compilation of the components so that it can be consumed by the browser. In Angular, Typescript is used for writing components, and these components are which are not directly run by browsers. So for such purposes, we require View Engine to convert Typescript (TS) into JavaScript (JS). The Following are the three responsibilities of View Engine: In Template Parsing, template HTML pass to Template Data then moves toward angular interpreter and last DOM. Rest of View Engine Will be discussed in the next article. And check our other articles for learning more frameworks such as laravel, Code Igniter, Django, etc.

KOTLIN Kotlin is an open source programming language like Java but kotlin syntac is may not be similar to Java, whereas, internally kotlin is reliant on the existing Java class library to produce wonderful results for the programmers. It is a general purpose, statically types programming language for the JVM and Android and it combines the OOPs (object oriented programming languages) features. Kotlin is developed by JetBrains in 2010 and has been open source since 2012. The main motive behind developing Kotlin is to provide code safety, clarity and interoperability to the developers around the world. Design Pattern of Kotlin Here are many design patterns of Kotlin. We briefly explained that patterns below Singleton Singleton is a first design pattern comes to the mind when we talk about Kotlin patterns.  It’s built right into the language. Behold, Object; JustSingleton.value will be now available from anywhere in the package. And it’s not a static initialization. Decorator If we talk about Decorator. We know the one that allows us to add a bit of functionality around some other class. Earlier IntelliJ would generate them for you. But it goes further now.  Here is one more thing HashMap that gets excited each time a new key is added?We have by keyword, with the help of this keyword we can define a backing instance in the constructor and delegate all the methods.Note: – If you want to access your own map with square brackets, and have all other methods work as before Factory Method To implement FactoryMethod we have Companion object that will allow us to implement this method in very easy manner. How to initialize an object where you want to control the object. Possibly because it has some covert stuff to do inside. Strategy Last design pattern principle for today is Strategy. This one is super easy because Kotlin has higher order functions. To change behavior at runtime, you should keep a point on mind that it’s indeed a Strategy pattern, and changing signature won’t work. Multiplatform Programming Language It is very explicit goal for Kotlin to work on all platforms, but we see it as a premise to a much more important goal: sharing code between platforms. As I told you that it a multiplatform programming language so it can handle any and all components of a modern application with the help of all other platforms like JVM, Android, JavaScript, Windows, Mac, Linux, iOS and even embedded system. How Kotlin works as Multiplatform Language Well we are using word multiplatform again and again but it does not mean that its mean is compiling all code for all platforms. Yes of course, model has its own limitations, and we know that modern applications need access to unique features of the platforms they are running on.  Kotlin does not limit us to the common subset of all APIs in the world. Each component can share codes with others but it can access APIs of platform at anytime through actual or expect mechanism provided by the language.
