My first attempt at the reverse text string converted the text string into an array and then reversed it since the array object has the reverse method. I know there's a way, but I couldn't figure out easily how to get rid of the commas. Here it is:

So I walked around thinking and came up with the idea to scrap the array method and use the charAt method and a for loop. I had to define the variable in the for loop as the last character in the string and then add to it, otherwise the reverse text included the value "undefined", like Matt would be "undefinedttaM". So here it is:

Ok. I went back to the book and figured it out the first one. This one splits the characters into an array, reverses the order and then uses the join("") method for the output.
