var romanToInt = function(s) {
    // There are seven symbols in the Roman numeral system. map each symbol to its value.
    const obj = { 
        'I': 1,
        'V': 5,
        'X': 10,
        'L': 50,
        'C': 100,
        'D': 500,
        'M': 1000
    }

    // store answer in result
    let result = 0;

    for (let i=0; i < s.length; i++){
        // current value from string
        const current = obj[s[i]];
        // next value from string
        const next = obj[s[i+1]];

        if (current < next){
            result += next - current; // IV -> 5 - 1 = 4
            i++; // increment i so we will move 2 characters to the right
        } else {
            result += current; // Current value is added to result
        }
    }

    return result;
