08. Fuel Tank - Part 2

function fuelTank(input) {
    let fuel = input[0]
    let liters = Number(input[1])
    let cart = input[2]
    let literPrice = 0

    if (fuel == 'Gas') {
        if (cart == 'Yes') {
            literPrice = 0.85;
        } else {
            literPrice = 0.93;
        }
    } else if (fuel == 'Diesel') {
        if (cart == 'Yes') {
            literPrice = 2.21;
        } else {
            literPrice = 2.33;
        }
    } else if (fuel == 'Gasoline') {
        if (cart == 'Yes') {
            literPrice = 2.04;
        } else {
            literPrice = 2.22;
        }
    }

    if (liters >= 20 && liters <= 25) {
        literPrice *= 0.92;
    } else if (liters > 25) {
        literPrice *= 0.9;
    }

    console.log(`${(literPrice * liters).toFixed(2)} lv.`)
}

Второ решение с тернарен оператор:

function fuelTank(input) {
    let fuel = input[0]
    let liters = Number(input[1])
    let cart = input[2]

    let literPrice =
        fuel == 'Gas' ? (cart == 'Yes' ? 0.85 : 0.93) :
            fuel == 'Diesel' ? (cart == 'Yes' ? 2.21 : 2.33) :
                fuel == 'Gasoline' ? (cart == 'Yes' ? 2.04 : 2.22) : 0;

    literPrice *= liters >= 20 && liters <= 25 ? 0.92 : liters > 25 ? 0.9 : 1;

    console.log(`${(literPrice * liters).toFixed(2)} lv.`)
