 This variable determines how ~tree-sitter-fold~ should fold each of the nodes 
defined in ~tree-sitter-fold-foldable-node-alist~. It is a nested alist, with 
the first key being the major mode, and second key being the 
~tree-sitter-node-type~. The value should be a function that takes a 
~tree-sitter-node~ as the single argument, and return a cons cell of buffer 
position as the range should be folded by ~tree-sitter-fold~. See 
~tree-sitter-fold-range-python~ for an example.

test out queries that determine what syntax nodes should be foldable and how to 
fold them. emacs-tree-sitter has 
[[https://ubolonton.github.io/emacs-tree-sitter/syntax-highlighting/queries/][an
 excellent documentation]] on how to write ~tree-sitter~ queries.
