Unfortunately, I still can't find a way to handle such case
that from

    export const add = (a, b) -!- => a + b;

typing 'C-M-f' should jump to the end of the next sexp
(to the end of whole "binary_expression"):

    export const add = (a, b) => a + b-!-;

since only tree-sitter knows about "binary_expression",
so 'forward-sexp-default-function' can't be used here.
