  While QZ Tray offers a free version, some features are restricted to the premium version, which may not be suitable for users looking for a completely free solution.
• Reliance on Java
  QZ Tray relies on the Java Runtime Environment (JRE), which can be a downside for some users due to potential security vulnerabilities and the need for additional installations.
• Browser Compatibility Issues
  Some users might experience compatibility issues with certain browsers, particularly as browser updates may affect how QZ Tray interacts with them.
• Support and Documentation

Possible disadvantages

• Internet Dependency
  The platform requires an internet connection to access the lessons and exercises, which can be inconvenient for users with limited or unreliable internet access.
• Limited Language Support
  The primary focus is on JavaScript, which may not benefit learners looking for comprehensive training in multiple programming languages.
• Self-motivation Required
  As an online learning platform, it requires a high level of self-discipline and motivation from learners to complete the course without the structure of a traditional classroom.
• Pace of Learning
  Learners may find the pace either too fast or too slow depending on their background and prior knowledge, as it's hard to tailor the content to every individual's learning speed.
