let word = "rps";
return word.charAt(randomNumGen());
}
let cpuInput;
if (randomLetterGen() == "r"){
cpuInput = "rock";
} else if (randomLetterGen() == "p"){
cpuInput = "paper";
} else if (randomLetterGen() == "s") {
cpuInput = "scissors";
}
return cpuInput;
}
console.log(getComputerChoice());
I think there is an undefined option because of the ‘let cpuInput;’ but I dont understand why. I thought the if statement redefined the variable. Also, the undefined option only logs when ‘Math.random()*3’ is 2 or above. It doesnt appear otherwise. Why?
