CertNotify VS JavaScript Operator Lookup

• Focused purpose
  CertNotify is built around monitoring SSL/TLS certificate expiration and sending alerts. A narrow focus like this usually means a simple setup, with no need to learn a large monitoring suite.
• Prevents outages
  Advance expiry warnings help teams renew certificates before they lapse. This avoids browser security warnings, broken APIs and lost customer trust.
• Low operational overhead
  As a hosted service, it needs no self-hosted infrastructure or scripts to maintain. You add your domains or endpoints and receive notifications.
• Useful for multiple domains
  Centralized tracking suits teams or agencies that manage many certificates across domains, subdomains and clients. Everything is visible in one place instead of in scattered calendar reminders.
• Alerts to the right people
  Notification-based workflows let you reach the relevant people, such as sysadmins, DevOps or account owners, before a certificate expires. This reduces the risk of one person's forgotten renewal.

• 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• Potential for Outdated Information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.

• Variable Operator using Boolean?

  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
