I was struggling with the replace method and you made me realize that while I was using .replace(x, y) correctly, I forgot to actually set the value equal to my variable 🤦

Thank you for the helpful video overall though

But how do you replace/append to a line already printed to the console, like if you wanted to print the numbers first, like
1.
2.
3.
4.
and then go back to write in front of each number to try to create sort of an effect...?
