JSDoc features and specs

  • Improved Documentation
    JSDoc generates detailed HTML documentation from comments, which improves the maintainability and readability of the codebase.
  • Enhanced Code Understanding
    By using JSDoc, other developers can easily understand the purpose and usage of functions, parameters, classes, etc.
  • Autocomplete and Type Checking
    When integrated with editors like Visual Studio Code, JSDoc comments can provide better autocomplete suggestions and can be used for TypeScript-like type checking.
  • Consistency
    JSDoc enforces consistent documentation across the codebase, ensuring that all parts of the code are equally documented.
  • Easy to Use
    It is relatively straightforward to incorporate JSDoc comments into existing JavaScript code with minimal effort.

    JSDoc supports various formats and tags, making it versatile for different documentation needs.

Possible disadvantages of JSDoc

  • Learning Curve
    New users may need some time to fully understand and utilize all the features and tags available in JSDoc.
  • Manual Effort
    Writing JSDoc comments requires a manual effort from developers, which can be time-consuming especially for large codebases.
  • Not Enforced
    Without proper enforcement, developers might omit JSDoc comments, leading to inconsistent documentation.
  • Overhead
    Too many comments can make the codebase cluttered and harder to navigate in some cases.
  • Limited to JavaScript
    JSDoc is primarily designed for JavaScript, which can be limiting if the project includes multiple languages.

Possible disadvantages of Datadog

  • Cost
    Datadog can become quite expensive, especially as the volume of monitored data and the number of integrations increases. This can be a limiting factor for smaller businesses.
  • Complexity
    With its extensive feature set, Datadog can be overwhelming for new users, requiring a steep learning curve to master all functionalities.
  • Data Retention
    The default data retention period is often shorter than what some organizations require, leading to additional costs for longer retention.
  • Performance Overhead
    The extensive data collection and monitoring capabilities can add performance overhead to the monitored systems, potentially impacting their performance.
  • Customization Limitations
    While Datadog provides extensive dashboards and visualizations, some users find the customization options to be limited compared to other monitoring solutions.
  • Support
    Some users have reported that the customer support can be slow or insufficient at times, which could be a downside when facing critical issues.

The Best Cloud Cost Management Tool: An Expert Guide (2026)
If observability is covered by Datadog: Datadog answers *why* costs are high (e.g., a memory leak), but a FinOps tool answers *what* to do about it (e.g., resize the instance). If your primary need is correlating performance to cost, Datadog is excellent. If you need to automate the remediation of idle, oversized, or poorly scheduled resources, the gap is significant and a...

  • Express Setup: Simple & Scalable
    In our JSDoc comments we describe our endpoints to using a set of tags, you can look at the different tags and what they do over on JSDoc's website but here's what we've used and why. - Source: dev.to / over 1 year ago
  • Connecting the Custom Elements Manifest to Figma Code Connect
    Most analysers that generate a Custom Elements Manifest operate by extending JSDoc comments. In our case, we'll need to add a @figma tag to our component comments so that we can tie the two together. The URL provided here can be found by selecting the main component in Figma and copying the link. Both the file name and node-id are key pieces of information that we'll need to query the Figma API later. - Source: dev.to / 9 months ago
  • Ask HN: Abandoned/dead projects you think died before their time and why?
    If your IDE supports JSDoc, then TS isn't needed for basic type constraints. https://jsdoc.app/. - Source: Hacker News / 10 months ago
  • Documenting Web Components With Storybook
    One of the best tools available in Web Component development is the Custom Elements Manifest. It's a JSON representation of all your available components, covering all the attributes, methods, slots and events they support, powered by your JSDoc comments and TypeScript types. You can customize the manifest generation through plugins to support custom JSDoc comments, allowing you to power more pieces of your... - Source: dev.to / over 1 year ago
  • Just Say No to JavaScript
    I've seen several ways of annotating Javascript that IDEs seem to understand. They usually involve using comments before fields, classes, or functions. The most compliant one seems to be using [JSDoc](https://jsdoc.app/). JSDoc is mostly intended for generating documentation. However, the Typescript compiler can validate types (and can even interoperate with Typescript definitions), if you configure it as such. In... - Source: Hacker News / over 1 year ago

  • Send the logs of your Shuttle-powered backend to Datadog
    Ideally, if we had access to the underlying infrastructure, we could probably install the Datadog Agent and configure it to send our logs directly to Datadog, or even use AWS Lambda functions or Azure Event Hub + Azure Functions in case we were facing some specific cloud scenarios. - Source: dev.to / almost 3 years ago

  • Post-DockerCon spam
    .. Is to see you email address being silently distributed to every single company that I've watched a talk from. And now suddenly get several promotional spam emails per day from some 4-5 different domains like instana.com, datadoghq.com, snyk.io, cockroachlabs.com (some of them send even multiple emails per day!).

  • Never write a UserService again
    We're commonly doing this with logging, using services such as Loggly or DataDog. We're using managed databases, be it on AWS, Heroku or database-vendor-specific solutions. We're storing binaries on S3. Externalising user authentication and authorization might be a good candidate as well. - Source: dev.to / over 5 years ago
