On-line Cadeia Reversa

I started learning Javascript recently, and as a little challenge I tried to create a program where a prompt asks for a name, and then the program prints the name out in reverse. My thinking was as follows:

var name = prompt("What is your name?");name = new Array(name.length);name.reverse();document.write(name);

What's wrong with this code?

Can anyone help me with the assignment - I have to reverse a string by using def. I am not allowed to use approaches like [::-1] or .reversed...The following function works, but prints vertically:

def ex1(name):        for x in range(len(name)-1,-1,-1):        print(name[x])kroYweN

how do I put the letters back into horizontal order?? Anyone? Thanks!

Converting String into Bytes: getBytes() method is used to convert the input string into bytes[].Method:

1. Create a temporary byte[] of length equal to the length of the input string.
2. Store the bytes (which we get by using getBytes() method) in reverse order into the temporary byte[] .
3. Create a new String abject using byte[] tostore result.

I expect the output to be : skeg

How do you reverse a string in place (or in-place) in JavaScript when passed to a function with a return statement? All without using the built-in functions? .reverse(), .charAt(), etc.

Say you have this string:

ABCDEFGH

And you want to reverse it so that it becomes:

GHEFCDAB

What would be the most efficient / pythonic solution? I've tried a few different things but they all look horrible...

Thanks in advance!

Update:

In case anyone's interested, this wasn't for homework. I had a script that was processing data from a network capture and returning it as a string of hex bytes. The problem was the data was still in network order. Due to the way the app was written, I didn't want to go back through and try to use say socket.htons, I just wanted to reverse the string.

Unfortunately my attempts seemed so hideous, I knew there must be a better way (a more pythonic solution) - hence my question here.
