imenu is a framework for mode-specific buffer indexes

Does this mean that it can list the function names depending on the programming
language mode ?

That's what the language mode should provide, yes, but strictly 
speaking it depends on the mode.

Do you have a particular mode in mind? Its code can be examined.

For example, java-ts-mode contains

  (setq-local treesit-simple-imenu-settings
              '(("Class" "\\`class_declaration\\'" nil nil)
                ("Interface" "\\`interface_declaration\\'" nil 
                nil)
                ("Enum" "\\`record_declaration\\'" nil nil)
                ("Method" "\\`method_declaration\\'" nil nil)))

(and then there is glue in the generic treesitter code)

Cheers,

Am currently working on elisp code.  imenu makes categorisation by variables
etc.  Can one remove the categorisation, and make it list only the function
names, or the variables, or the consts ?

Have done this function, but cannot get imenu to run and show the function names
It seems to require arguments, but I do not know what has to be done.

(defun vodil-imenu-function-list ()
  "Set up `imenu` to show a list of functions in the current buffer."

  (interactive)
  (setq imenu-generic-expression
         '((nil "^(defun\\s-+\\([^ \t\n]+\\)" 1)))
  (imenu-add-to-menubar "Function List")
  (imenu))

Have split the regexp strings this way, but getting into problems when
using concat.

  (setq imenu-generic-expression
        `( ("Functions"
              ,(concat "^\\s-*"
                       "(defun\\s-+\\([[:word:]-]+\\)") 1)
           ("Variables"
              ,(concat "^\\s-*"
                       "(\\(defvar\\|defvar-local\\|defconst\\)"
                       "\\s-+\\([[:word:]-]+\\)")  2)))
