This is the code my YouTube teacher used to create rock paper scissors game. My problem is, score shows undefined. It worked just fine before LocalStorage lessonsā¦I asked ChatGPT and Bard for help too and the YouTube channel is remains unresponsive.
Can someone help me? Iām 100% sure itās some dumbass error Iām missing.
