//This is a comment,
/*so is this*/

Not in JavaScript itself, but some editors will treat it like a JSDoc (https://github.com/jsdoc3/jsdoc) comment to help with autocomplete, etc.
You can also run your code through something like JSDoc to automatically generate HTML documentation for your codebase.
