const calculate = async () => {
    const val1 = await getValue(1) // remote call, will take 1 sec
    const val2 = await getValue(2) // remote call, will take 1 sec
    const val3 = await getValue(3) // remote call, will take 1 sec

    // can i get answer faster than 3 seconds ?
    return va1 + val2 + val3
