Cons
Con Only provides an output of the API
JSDoc only provides a linear output of the API and not really a visually appealing or any information other than the methods and what they do. It's very technical so it may be hard for beginners to read documentation generated by it and understand it.
Con Missing templates
The docuementation generated is really simple. It does need more elaborated template. A beautiful documentation is more easy to read...
Con No documentation/tutorial
Hard to configure and there is almost no documentation or clear example/tutorial.
