First, we know that characters are accessed by index. In fact, we can access a given character with the charAt method. (keyboard faintly clicking) The last character in the string is located at the length of the string minus one. (keyboard faintly clicking) We can combine these two ideas to find the last character in the string. The string in question is the text, so we'll run charAt on that string.

Then we subtract one here because indices start at zero. This will give us the last character in the string. Let's run it. Our code works as expected. Now, you might be thinking that…
