Arrays Stage 4 Exercises 2 of 2

I'm trying to sort an sayings2[ ] by string length. For some reason this isn't clicking for me. I've watched the video twice and tried to figure it out on stackoverflow and w3 school without any luck. Can somebody please explain this to me.

<!DOCTYPE html> <html lang="en"> <head> <title> JavaScript Foundations: Arrays</title> <style> html { background: #FAFAFA; font-family: sans-serif; } </style> </head> <body> <h1>JavaScript Foundations</h1> <h2>Arrays: Methods Part 1</h2> <script> var saying1 = ["The", "quick", "brown", "fox", "jumps", "over", "the", "lazy", "dog"]; var saying2 = ["The", "quick", "brown", "fox", "jumped", "over", "the", "lazy", "dog's", "back"]; saying1.reverse(); sayings2.sort(function(a,b){ return a.length < b.length});

</script>

</body> </html>

copy and pasting that code didn't quite turn out right. Here is the link on code pen: http://cdpn.io/pcAbm

Rewatch the 'Return a-b' part, that function as an argument is how you solve it.

a.length & etc.

for one you have an unneeded "s" in your variable name: "sayings2" should be "saying2"

instead of using the < comparison I switched to -

saying2.sort(function(a,b){ return a.length - b.length});
