  Without the ability to save results over time, users cannot easily track improvement or compare past performance in a structured way.

• 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.
