  For large-scale applications or extensive use of advanced features, the costs can add up, making it potentially expensive.
• Vendor Lock-in
  Relying heavily on Ably’s platform-specific features may result in vendor lock-in, making it challenging to switch to other services in the future.
• Dependence on Internet Connection
  As a cloud-based service, Ably’s performance is highly dependent on the quality and reliability of the internet connection.

• Progress Tracking
  Learners can monitor their progress through the course, setting goals and milestones to keep themselves motivated.

Possible disadvantages

• Cost
  While there are free resources available, full access to all features and content often requires a paid subscription, which might be a barrier for some users.
• 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.
