  • Ease of Use
    The JavaScript Operator Lookup tool provides a simple and easy-to-use interface for developers to quickly find information about JavaScript operators, improving their coding efficiency.
  • Comprehensive Information
    The tool offers a comprehensive list of JavaScript operators along with detailed explanations, examples, and related information, which can be very helpful for both beginners and experienced developers.
  • Time-Saving
    By consolidating information about JavaScript operators in one place, the tool saves developers time they might otherwise spend searching through documentation or other online resources.
  • Educational Resource
    The tool acts as an educational resource by not only listing operators but also explaining their functionality and use cases, aiding in the learning process.
  • Responsive Design
    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  • Potential for Outdated Information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
