Function: js-json-mode

js-json-mode is an autoloaded, interactive and byte-compiled function defined in js.el.gz.

Signature

(js-json-mode)

Documentation

Major mode derived from prog-mode by define-derived-mode.

It inherits all of the parent's attributes, but has its own keymap, abbrev table and syntax table:

  js-json-mode-map, js-json-mode-abbrev-table and
js-mode-syntax-table

which more-or-less shadow prog-mode's corresponding tables.

In addition to any hooks its parent mode might have run, this mode runs the hook js-json-mode-hook, as the final or penultimate step during initialization.

Probably introduced at or before Emacs version 29.1.
