[Coding Challenge help] Update the variable of 'tenthCharacter' on about line 20, to get the tenth character ....

<!DOCTYPE html> <html lang="en"> <head> <title> JavaScript Foundations: Strings</title> <style> html { background: #FAFAFA; font-family: sans-serif; } </style> </head> <body> <h1>JavaScript Foundations</h1> <h2>Strings: Methods</h2> <script> var quick = "The quick brown fox jumps over the lazy dog"; var tenthCharacter = quick.charAt(9);

</script>

</body> </html>

So basically its asking for the 10th character in the string assigned to the variable quick. Seeing as JS starts its count from 0, you'd think the answer would be "b" or quick.charAt(10)

but instead if you try that it'll show an error saying they expected an empty string or " " as the answer... but the " " is located at the 9th index...

I have the right answer, I just wanted to bring this (possible bug?) to the attention of teachers as this could be a confusing error for complete noobies.

Well, the right answer is definitely var tenthCharacter = quick.charAt(9);, since index 9 is the 10th character and it is ' '. Space is the 10th character (from natural, intuitive human perspective), but human 10th character is indexed as 9 in most programming languages.
