Dart vs GWT: What are the differences?
Introduction
Dart and GWT are both programming languages used for web development, albeit with some key differences. In this markdown, we will highlight the distinct features and characteristics of Dart and GWT.
1. Dart for Web vs. GWT for Java Developers
Dart is a programming language specifically designed for web development, whereas GWT (Google Web Toolkit) is primarily meant for Java developers. Dart provides a complete development ecosystem for web applications, including a virtual machine, libraries, package manager, and a modern syntax. On the other hand, GWT allows developers to write client-side web applications in Java, which are then compiled to JavaScript for execution.
2. Syntax and Compilation
Dart uses a single-language approach, where code is written in Dart and directly executed in its virtual machine or transpiled to JavaScript for compatibility. GWT, on the other hand, uses a two-language approach. While developers write code in Java, it is ultimately compiled to JavaScript, which is then executed in the browser. This compilation step in GWT allows for optimizations and is aimed at maximizing performance.
3. UI Development
Dart comes with a built-in library called "Flutter" that provides a framework for building UIs for mobile, web, and desktop applications. This allows developers to create responsive and visually appealing user interfaces using a single codebase. In contrast, GWT lacks a dedicated UI library and relies on the web standards like HTML, CSS, and JavaScript, requiring developers to work with these technologies directly.
4. Tooling and Ecosystem
Dart offers a comprehensive set of development tools, including an IDE called "DartPad," a package manager called "pub," and a testing framework called "unittest." It also has a strong ecosystem with support for various libraries and frameworks. GWT, being focused on Java, benefits from the wide range of Java IDEs and build tools available. Additionally, GWT has a vibrant community and extensive documentation, making it easier for developers to find resources and solve problems.
5. Debugging and Productivity
One advantage of Dart is its ability to provide a debugger that can directly debug Dart code in the browser, similar to how developers debug JavaScript. This feature simplifies the debugging process and helps developers identify and fix issues more efficiently. GWT, on the other hand, requires developers to debug the Java code running in the browser, which can be more complex and time-consuming.
6. Language Features and Flexibility
Dart is a modern, object-oriented language with support for features like strong typing, lambdas, and async/await for handling asynchronous tasks. It offers a more flexible and expressive syntax, making the code easier to read and maintain. GWT, being based on Java, inherits the language's features and syntax but lacks some of the modern language constructs found in Dart.
In summary, Dart and GWT differ in their focus, syntax, UI development approach, tooling, debugging capabilities, and language features. Dart is designed specifically for web development, with a modern language and UI framework, while GWT is targeted towards Java developers, using Java as the primary language and compilation to JavaScript.
Can anyone help me decide what's best for app development or even android Oreo development? I'm in a state dilemma at the moment. I want to do Android programming, not necessarily web development. I have heard a lot of people recommend one of these, and it seems that both the tools can do the job. Which language would you choose?
I assume that you mean Flutter by Dart. I have over 6 years experience programming in Android SDK, but about 1,5 month in Flutter. So far I think that Flutter is the future for mobile development. Flutter SDK is much better designed. Ecosystem of libraries seems having much higher quality. I would even say that android opensource libs are having really poor quality. Many times I am wondering how can garbage like that have so many stars at GitHub. Android SDK is hard to compose so you reinvent even basic things on and on, which is totally different story at Flutter. Lolcycle? Both are having good documentation. I quess apps in Flutter can be done in 1/3 of time compared to develop AndroidSDK and iOS, its design is that much better and contemporary. As of language comparison - Kotlin is better, but the difference is not that important. Go from one language to other is no problem. Dart is being updated with new features.
I've selected Flutter and Dart for my side projects and never regretted. Dart learning curve is easy after any OOP language . Flutter as a framework is also has a low entry threshold. I've already started development after a week of learning. Pros for me: code can be build for Android and IOS devices (for ios you need mac or VM), apps written in Dart have great performance on each of these platforms, flexibility. Cons: if you want to build a product as a business and want to hire a new Flutter Developer in the future it can be a problem as the framework and language is not popular for the moment.
I have worked in mobile development since 2010. I have experienced myself on various techs including Native SDK (Android), React Native (from 2016) and Flutter (2018). Almost the apps nowadays can be built using cross-platforms frameworks like React Native or Flutter. I suggest you start with Flutter. Flutter SDK is designed well to speed up your development and it still keeps the quality for your apps. If you're familiar with OOP languages (Java, C#...), switching to Dart is really quick and easy. Of course, sometimes you will need to dive deep into native parts but almost the cases you don't need. Good luck!
It depends on what is the purpose of your app development. Do you want to make one app that shares the codebase for both iOS and Android? If yes, then Dart is the way to go. Does your app include interacting with hardware features like camera, Bluetooth, if yes, then go for native Android for better performance? Dart is good for simpler UI apps where you just do basic crud operations over the network and show data but if you need richer UI experience go with native.
I am currently learning web development with Python and JavaScript course by CS50 Harvard university. It covers python, Flask, Django, SQL, Travis CI, javascript,HTML ,CSS and more. I am very interested in Flutter app development. Can I know what is the difference between learning these above-mentioned frameworks vs learning flutter directly? I am planning to learn flutter so that I can do both web development and app development. Are there any perks of learning these frameworks before flutter?
Hey Muhamed, For web development, you'll have to learn how to write backend APIs and how to build UI for browsers, apps, etc. If you're just starting off with programming, I'd suggest you stick to one language and trying developing everything using it to cut the unnecessary learning overhead. Although Python and JavaScript are very similar for beginners, JavaScript is the only available option for both frontend and backend development for a web application. You can start working with Node.js for your API development and Vanilla JS along with HTML/CSS for UI. You'll only need to learn one language to do all of this. Hope this helps.
Flutter is good for everything and it is getting better as I am speaking. Flutter Web is almost ready for production and I have made 2 complex working websites already.
From a management and hiring perspective, I recommend Flutter (Dart). It provides native solutions to both mobile platform ( (Android and IOS) while having the same knowledge. Hiring managers look at this as an advantage since a developer can provide solutions for both platforms whit the same knowledge. The Flutter framework is growing and there is a lot of resources to ground your knowledge and start experimenting. Dart is also a great language that covers most E2E necessities, so again, no further need of learning one language for FE and another for BE and services. It is my belief that Dart will surpass Kotlin soon, and will leverage to Python and Java in the upcoming year.
Well. Flutter is just a Framework (just like Django btw.) and it uses Dart as a programming language. Django is kind of solving a different problem than Dart. Dart is intened for use in Front End Applications and Django is a Framework for Back-End Web Development.
So if you want to program Flutter Apps (although i wouldn't recommend it for any serious web development yet since Flutter web isn't very mature yet) i would recommend you just lern Dart.
If you are interested in Flutter, learn it on your own time, parallel to the course. No matter what order you do them, eventually you will end up learning them all anyway ;-)
JavaScript is at the forefront of our entire development approach. Not only do we use different JavaScript frameworks and management tools, but we also use pure vanilla JavaScript to solve simple problems throughout all of our client's builds. JavaScript is a general purpose programming language that can be blazing fast and fun to work with. There's not one project we are working on that doesn't involve it.
