Hello everyone. I’m at Arrays and Function, exercise 10. I just want to confirm that what is happening in this exercise is that we are changing the value of the global scope by changing the string ‘mutated’ to ‘MUTATED’ and then .pop it off. Considering where the braces {} are I just want to confirm.
