In the following (from <https://nim-lang.org/docs/backends.html)>, what is the
point of using "{.importc.}"
Apparently it can be omitted : The example hereunder works even without it:
<html><body>
<script type="text/javascript">
function addTwoIntegers(a, b)
{
return a + b;
}
</script>
<script type="text/javascript" src="calculator.js"></script>
</body></html>
Run
addTwoIntegers(a, b: int): int {.importc.}
when isMainModule:
echo addTwoIntegers(3, 7)
Run
nim js -o:calculator.js calculator.nim
Run
