We have collected here some useful links to help you find out if JSDoc is good.
Check the traffic stats of JSDoc on SimilarWeb. The key metrics to look for are: monthly visits, average visit duration, pages per visit, and traffic by country. Moreoever, check the traffic sources. For example "Direct" traffic is a good sign.
Check the "Domain Rating" of JSDoc on Ahrefs. The domain rating is a measure of the strength of a website's backlink profile on a scale from 0 to 100. It shows the strength of JSDoc's backlink profile compared to the other websites. In most cases a domain rating of 60+ is considered good and 70+ is considered very good.
Check the "Domain Authority" of JSDoc on MOZ. A website's domain authority (DA) is a search engine ranking score that predicts how well a website will rank on search engine result pages (SERPs). It is based on a 100-point logarithmic scale, with higher scores corresponding to a greater likelihood of ranking. This is another useful metric to check if a website is good.

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 / about 1 year ago
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 / 8 months ago
If your IDE supports JSDoc, then TS isn't needed for basic type constraints. https://jsdoc.app/. - Source: Hacker News / 8 months ago
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
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
If you choose to use JSDoc instead of TypeScript, this only con that TypeScript has is gone, but a new one appears: JSDoc doesnt work very well with more complex types if you dont use classes to represent them. - Source: dev.to / over 1 year ago
Thanks to JSDoc it's easy to write documentation that is coupled with your code and can be consumed by users in a variety of formats. When combined with a modern publishing flow like JSR, you can easily create comprehensive documentation for your package that not only fits within your workflow, but also integrates directly in the tools your users consume your package with. This blog post aims to cover best... - Source: dev.to / about 2 years ago
Note: For simplicity, I will omit the JavaScript documentation, but for a production grade code you may want to add the documentation (see jsdoc.app website for more). - Source: dev.to / about 2 years ago
You may like JSDoc[1] if you just want some type-safety from the IDE without the compilation overhead. Itโs done wonders when Iโve had to wrangle poorly commented legacy JavaScript codebases where most of the overhead is tracing what type the input parameters are. Personally, Iโm impartial to TypeScript or JSDoc at this point. But Iโd rather have either over plain JavaScript. [1] https://jsdoc.app/. - Source: Hacker News / about 2 years ago
I wholeheartedly agree. At most, I introduce JSDoc[1] to newer developers as standardising how parameters and whatnot are commented at least gets you better documentation and _some_ safety without adding any TS knowledge overhead. [1] https://jsdoc.app/. - Source: Hacker News / over 2 years ago
The best way to do this, of course, is with JSDoc. But something I always found awkward about jsdoc is defining the object types in the same file. So, after a lot of reading, I found a way to combine JSDoc with declaration type files from Typescript. Let me give you an example:. - Source: dev.to / over 2 years ago
There is a lot of specific symbols presented on the JSDOC specification that can be found here: https://jsdoc.app. - Source: dev.to / over 2 years ago
JSDoc is a specification for the comment format in JavaScript. This specification allows developers to describe the structure of their code, data types, function parameters, and much more using special comments. These comments can then be transformed into documentation using appropriate tools. - Source: dev.to / over 2 years ago
Working with new features, frameworks, and tools, the experience of reading documentation is a critical part of it. I have been lucky to work with projects that feature really easy to read documentation such as USWDS and Bun, but I've also had the misfortune to work with pretty terrible documentation like JSDoc. The JSDoc documentation lacks a search field which makes searching for specific items an ordeal and... - Source: dev.to / over 2 years ago
The Svelte team followed suit but motivated by the maintainer's developer experience as they migrated the project away from TypeScript in favor of plain JSDoc comments for type annotations instead. - Source: dev.to / over 2 years ago
Even more relevant, tools like Javadoc, JSDoc, Doxygen, etc. Read comments in a specific format to generate documentation. These comments do not affect readability. On the contrary, Javadocs are great for explaining how to use these entities. Combined with tools like my dear Doctest, we even get guarantees of accuracy and correctness! - Source: dev.to / over 2 years ago

Use JS Doc and Typescript for full editor annotation and autocomplete. Source: about 3 years ago
JSDoc remains a prominent tool in the landscape of JavaScript development, primarily recognized for its capabilities in generating clean and effective documentation from annotated code comments. This utility is regarded as the JavaScript equivalent of what Sass does for styling, emphasizing its role in swiftly creating well-organized documentation. One of JSDoc's significant advantages lies in its integration with modern web development practices, especially its compatibility with tools like Storybook, where it aids in generating Custom Elements Manifests. This feature is particularly beneficial for representing web components' attributes, methods, slots, and events, thereby enhancing the quality and depth of component documentation.
When discussing JavaScript and its alternatives, JSDoc is often positioned as a viable middle-ground for developers seeking type safety without fully committing to TypeScript. It offers some level of type validation via comments, which can be advantageous for projects where a full TypeScript conversion is impractical. This function is particularly valued when dealing with legacy JavaScript codebases that lack proper annotation, as it can provide clarity without imposing significant overhead.
Despite the utility it offers, JSDoc does face criticisms. A noted shortcoming is its struggle with more complex type definitions if developers avoid using classes for representation. Furthermore, JSDoc's documentation itself has been critiqued for lacking comprehensive search features, which can make navigating and finding specific information cumbersomeโa point raised by users who appreciate more robust documentation systems like Docusaurus.
In practice, many developers leverage JSDoc alongside other languages and tools to enhance productivity. It is regularly used in tandem with TypeScript to not only generate TypeScript types but also to bolster JavaScript code with type checking capabilities. This combination provides a well-rounded development experience, balancing robust type safety with the flexibility and rapid prototyping characteristic of JavaScript.
Its application is widespread across various development stages, from documenting APIs and JavaScript packages to maintaining large codebases. Some teams, like those working on Svelte, have shown interest in using JSDoc as a lighter alternative to TypeScript, highlighting its potential to streamline workflows without sacrificing code documentation and maintainability.
In summary, JSDoc stands as a versatile tool in a developer's arsenalโmost effective when used for generating clear, concise documentation and providing lightweight type safety in JavaScript projects. While it has its limitations, particularly with complex type handling and suboptimal internal documentation search capabilities, its integration into modern development workflows, interoperability with TypeScript, and ease of use help maintain its popularity among developers seeking efficient and straightforward documentation solutions.
