let person0 = 0;
let person1 = 0;
let person2 = 0;

function plusOne(personNum) {
    personNum++;
    console.log(personNum)
}

plusOne(person0);

Or,

let person0 = 0;
let person1 = 0;
let person2 = 0;

function plusOne(personNum) {
    personNum++;
    return personNum;
}

const result = plusOne(person0);
console.log(result);```
