Hi guys, I've been programming quite a while in JS. But am a newbie to
Node. What a great app learnyounode is!
But this baffled me, perhaps someone cal explain this to me:
'strict mode';
var result;
for (var i = 2; i < process.argv.length; i++) {
result += Number(process.argv[i]);
}
console.log(result);
This always returned NaN. When I console log each iteration, I always end
up with an extra iteration which has the value of NaN. Adding them up
results into NaN.
But when I do this:
'strict mode';
*var result = 0;*
for (var i = 2; i < process.argv.length; i++) {
result += Number(process.argv[i]);
}
console.log(result);
Everything is fine and the program works as expected.
Who can enlighten me??
