Is it possible to inject the value of a macro into code using a variable?
I set a macro called ‘version’ with a version number at the top of my .org file. I would like to do something like this:
#+macro:version Version 0.2.5
#+name:code-name
#+begin_src js :tangle some-file.js :var ver={{{version}}} :exports both :results output
const version = ver;
#+end_src
When this code is evaluated during export, there is an error:
org-babel-ref-resolve: Reference ‘{{{version}}}’ not found in this buffer
Regards,
Wesley

No, macros are mostly text replacement. They are not Babel related.
You may want to pass arguments to Babel blocks using other Babel blocks.

I use properties for this, as in:
#+begin_src org
,#+property: version 2.0.5
,#+header: :var version=(esf/get-parameter "benzenefeed")
[...]
,#+begin_src somelanguage
[... code that uses version ...]
,#+end_src
#+end_src
where
#+begin_src emacs-lisp
(defun esf/get-parameter (p)
(let ((value (org-entry-get (point) p 'inherit)))
(message "parameter %s value obtained %s" p value)
(if value
(if (string-match-p "^[-+ ]*[[:digit:].]+$" value)
(string-to-number value)
value)
(error "Property parameter \"%s\" not known." p))))
#+end_src
