How can I use /* ... */ comments instead of // comments?

[lumenwrites]

Hi! I'm new to this mode, can you help me to figure out how to tell emacs to comment stuff like this /* ...*/ when I press M-;? All my comments are using this format, and without this feature it becomes very difficult to adjust.

This should work pretty well (stolen from css-mode)

(add-hook 'js2-mode-hook
	  (lambda ()
	    (setq-local comment-start "/*")
	    (setq-local comment-start-skip "/\\*+[ \t]*")
	    (setq-local comment-end "*/")
	    (setq-local comment-end-skip "[ \t]*\\*+/")))
