In chapter 7 there is a problem with the declaration of a table in .wat

;; for example math.wat
(table (export "tbl") anyfunc (elem $add $sub)) 

returns errors:

math.wat:12:24: error: unexpected token "anyfunc", expected a natural number (e.g. 123).
        (table (export "tbl") anyfunc (elem $add $sub))
                       ^^^^^^^
math.wat:12:43: error: undefined table variable "$sub"
        (table (export "tbl") anyfunc (elem $add $sub))
                                          ^^^^

I found a fix here in paragraph Defining Tables in Wasm and the following syntax works

(table 2 funcref) ;; 2 is the initial size funcref is the element type
	(elem 
	(i32.const 0) ;; a memory offset to start populate the table
	$add $sub) ;; the content of the table

not sure whether this is the actual fix though.
By the way: your book is amazing! Congrats!

      console.log(instance.exports.log_how_old(2021, 2000));  

afaict log_how_old calls a function that calls console.log. why wrap the call in yet another console.log ?

(hi brian).

A few days ago I bought "WebAssembly: The Definite Guide". I started with chapter 5, which is the most relevant to me.

Environment:
Windows 64-bit
MSYS2 installed in C:\msys64\mingw64

Observed:
PS S:\Git\bsletten\wasm_tdg\ch05> clang --target=wasm32 -nostdlib -Wl,--no-entry -Wl,--export-all howold2.c -o howold2.wasm

+ CategoryInfo : ParserError: (:) [], ParentContainsErrorRecordException
+ FullyQualifiedErrorId : MissingArgument

Expected:
Working example explained, also for Windows users.

Workaround?
I tried a few code variations, but these attempts failed.

Note:
LLVM in Windows expects Microsoft Visual Studio, which I don't have. I use VS Code (like many others do).

in howold.c, the function howOld can be simplified to:

int howOld(int currentYear, int yearBorn) {
  return currentYear - yearBorn;
}
