JavaScript features and specs

  • Wide Browser Support
    JavaScript is supported by all modern web browsers without the need for any plugins, making it highly versatile for client-side scripting.
  • Asynchronous Programming
    JavaScript supports asynchronous programming with features like callbacks, Promises, and async/await, which helps in efficiently handling tasks such as HTTP requests.
  • Rich Ecosystem and Libraries
    The JavaScript ecosystem includes a vast amount of libraries and frameworks like React, Angular, Vue, and Node.js, which streamline development processes.
  • Community Support
    JavaScript has a large and active community, providing extensive resources, documentation, and forums for troubleshooting and development advice.
  • Event-Driven
    The language is inherently event-driven, making it suitable for developing interactive web applications that react to user inputs.
  • Full-Stack Development
    With the advent of Node.js, JavaScript can be used for both client-side and server-side development, enabling full-stack development using a single language.

Possible disadvantages of JavaScript

  • Security Issues
    Being an interpreted language that runs in the browser, JavaScript code is visible to the user, making it susceptible to security risks such as Cross-Site Scripting (XSS).
  • Browser Compatibility
    While JavaScript itself is widely supported, different browsers may implement JavaScript functions and standards differently, leading to compatibility issues.
  • Performance
    JavaScript is generally slower than compiled languages such as C++ or Java. Heavy computations can lead to performance bottlenecks.
  • Single Inheritance
    JavaScript uses prototypal inheritance instead of classical inheritance, which can be confusing for developers coming from object-oriented programming backgrounds.
  • Dynamic Typing
    JavaScript's dynamic typing can lead to runtime errors that are hard to debug, as variable types are checked at runtime rather than during compilation.
  • Fragmentation
    The ecosystem has many competing libraries, frameworks, and tools, which can make it overwhelming for developers to choose the right technologies for their projects.

Qt / C++ features and specs

  • Cross-platform compatibility
    Qt allows developers to write applications once and deploy them across multiple platforms such as Windows, macOS, Linux, Android, and iOS. This significantly reduces development time and costs.
  • Rich set of libraries
    Qt provides a comprehensive set of libraries and tools for building both GUI and non-GUI applications, which helps developers create feature-rich applications without needing additional tools.
  • Strong community and support
    Qt has a large and active community, offering extensive documentation, forums, and third-party resources. This can assist developers in solving problems quickly.
  • Consistent API
    Qt offers stable and consistent APIs across versions, which helps in maintaining and updating applications with minimal effort.
  • Open-source availability
    Qt is available as an open-source framework under both commercial and LGPL licenses, providing flexibility for different types of projects.

Possible disadvantages of Qt / C++

  • Steep learning curve
    Qt, especially when used with C++, can have a steep learning curve for new developers due to its extensive framework and C++ complexity.
  • Commercial licensing costs
    While Qt is available as open-source, the commercial version can be expensive, particularly for small businesses or startups.
  • Binary size
    Applications built with Qt might result in larger binary sizes compared to applications developed with other frameworks, which could be a concern for resource-constrained environments.
  • Slightly outdated UI components
    Although Qt provides many UI components, some may appear dated compared to native components of modern operating systems, requiring custom styling for a modern look.
  • Limited mobile development features
    While Qt supports mobile platforms, it may not offer full access to native device features or as robust support as native mobile development tools, making it less ideal for certain mobile applications.

  • Check out my new drawing software PainterQt for Windows operating systems!!
    PainterQt is an open source drawing software written in C++ using Qt GUI creation technology. PainterQt is a personal project of mine that started with a few lines with the purpose of understanding how Qt's QPainter class works. The program grew and I decided to work on it in a serious project and then distribute it. I would love to see this dream of mine come true, so if you could take a look at the software and...

    Qt Looks like native widgets Lots of functionality Event based - can both be intuitive to understand and complex, but is efficient for CPU for typical desktop applications Lots of resources available. Source: over 2 years ago
  • Maui vs the alternatives (Avalonia, Flutter, Electron, etc)
    Have you tried Qt? It's a cross-platform framework written in C++. There are also bindings for Qt for other languages that allow you to write code in such languages (like Python). Source: over 2 years ago
  • QML for Python and poor community !!
    Can you suggest some tutorials and sources for QML and Python , I can't find any helpful sources (videos on YouTube / Project in github ) , except the qt.io but it's not enough and there are a few examples there . Source: over 2 years ago
  • Point me in the right direction please.
    Well, since you mention Qt... Install it with the Online Installer (https://www.qt.io/download-qt-installer, then ignore all the talk about commercial version, you do want the open source version). Just one version of Qt, probably the latest. For Windows, choose MingGW version of Qt and check that the matching MinGW is set to be installed too. If you have trouble, check out the installation instructions (should be... Source: over 2 years ago
