Possible disadvantages

• Dependency on Internet
  Since the tool is web-based, it requires an internet connection, which may not be available in all situations, potentially limiting accessibility.
• Scope Limited to Operators
  The tool focuses solely on JavaScript operators, which might not cover all the needs of a developer looking for comprehensive JavaScript resources or help with other language features.
• Potential for Outdated Information
  There is a potential risk of the information becoming outdated if the tool is not regularly maintained and updated to reflect the latest changes in the JavaScript language.
• Lack of Interactive Examples
