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.

Opera Add-ons features and specs

  • User Interface Customization
    Opera Add-ons provide a variety of extensions that allow users to customize the browser's appearance and functionality to better suit personal preferences.
  • Wide Range of Extensions
    The platform offers a broad spectrum of extensions, catering to diverse needs, from productivity tools to entertainment applications.
  • Opera VPN Integration
    Firefox Add-ons integrate with Opera's built-in features such as the VPN, offering additional privacy and security options to users.
  • Performance Enhancements
    Certain add-ons are designed to optimize browser performance, including tools for blocking ads and managing tabs, leading to a smoother browsing experience.
  • Developer Support
    Having a supportive infrastructure encourages developers to create and maintain extensions, fostering innovation and keeping the platform current.

Possible disadvantages of Opera Add-ons

  • Security Risks
    Some add-ons may pose security risks by requesting excessive permissions or containing vulnerabilities that could be exploited.
  • Compatibility Issues
    Certain extensions might not be compatible with all versions of Opera or may conflict with other installed add-ons, causing functionality problems.
  • Quality Variability
    The quality of add-ons can vary significantly, with some being poorly designed or maintained, which can lead to a subpar user experience.
  • Resource Consumption
    Some extensions can be resource-intensive, leading to slower performance and increased power usage, particularly if many are installed simultaneously.
  • Limited Availability
    Compared to more popular browsers like Chrome and Firefox, Opera may have a smaller library of extensions, limiting user choices.

  • Move tabs, saved stuff and passwords to new pc, how?
    For extensions, you can't back them up and restore them, so you'll just have to reinstall them from https://chrome.google.com/webstore/category/extensions and https://addons.opera.com/en/. If you bookmark the URL to each extension's page, and put those bookmarks in a folder, in the new Opera, you can just right-click on that bookmarks folder, choose "open all in tabs", and then click "Add to Opera" on each page to...
