这些代码在解构对象中是否有任何功能差异？

Question

While I'm using destructuring assignment to assign variables from arrays, I find another way of destructing. Is there any difference between these two codes?

This is a challenge from freeCodeCamp using javascript, ES6.

const LOCAL_FORECAST = {
  today: { min: 72, max: 83 },
  tomorrow: { min: 73.3, max: 84.6 }
};

function get_MaxOfTmrw(forecast) 
{
    const {tomorrow:{max : max_OfTomorrow}} = forecast;

    return max_OfTomorrow;
}

function get_MaxOfTmrw(forecast) 
{

    const {max : max_OfTomorrow}} = forecast.tomorrow;

    return max_OfTomorrow;
}

console.log(get_MaxOfTmrw(LOCAL_FORECAST));

Answer 1

There will be a difference only if it requires default values

function get_MaxOfTmrw(forecast)
{
    const { tomorrow: { max : max_OfTomorrow  = 0 } = {} } = forecast
    return max_OfTomorrow
}

function get_MaxOfTmrw(forecast) 
{
    const { max : max_OfTomorrow = 0 } = forecast.tomorrow; // what if tomorrow is undefined?
    return max_OfTomorrow;
}
