As part of the Javascript documentation family, it has the following advantages: 1. Easy to operate. There are only a few graphical document tools. 2. Analysis intelligence. You can help users complete comments based on the context so that users can write less comments as much as possible. 3. The output format is random. Most file generation tools generate a CHM File.
