    With a responsive design, the tool is accessible across different devices, ensuring that developers can use it whether they are on a desktop, tablet, or mobile device.

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  • Potential for Outdated Information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
    While the tool provides examples, the absence of interactive coding environments means users cannot test operators directly within the tool.

    If you replace your || with ?? You should get the behaviour you are after. This is a good reference for what the operators do in js: https://joshwcomeau.com/operator-lookup. Source: about 5 years ago
  • Donating the Model Context Protocol and Establishing the Agentic AI Foundation
    MCP is overly complicated. I'd rather use something like https://utcp.io/. - Source: Hacker News / 10 months ago
