Emacs mode to edit JSON

Question

Does anybody know a good Emacs mode to edit JSON? An app I am working on uses a JSON based communication protocol and having the data nicely indented and syntax-highlighted woul

Since JSON is a subset of YAML, yaml-mode works too (I don't know how it compares to js-mode and json-mode, though).

Install (from emacs): M-x package-install yaml-mode.

Association of yaml-mode with YAML and JSON files, in ~/.emacs.d/init.el:

(add-to-list 'auto-mode-alist '("\\.yaml$" . yaml-mode))
(add-to-list 'auto-mode-alist '("\\.json$" . yaml-mode))
