I HAVE A DOUBT THAT WHILE SOLVING DESTRUCTRING PROBLEM WHY IT IS ASIGNING TO FORECAST INSTEAD OF THE FIRST CONST LIVE_FORECAST

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

function getMaxOfTmrw(forecast) {
  "use strict";
  // change code below this line
  const {tomorrow: {max: maxOfTomorrow}} = forecast; // change this line
  // change code above this line
  return maxOfTomorrow;
}

console.log(getMaxOfTmrw(LOCAL_FORECAST)); // should be 84.6

Hi @talhaspartan!

It seems the problem is “use strict” in FCC. If you remove it you’ll pass the exercise (I tried myself).

the code is compiling but i want to know why we are using forecast …there

#5

NO , its not passing in free code camp its showing error in console like
“nested destructuring was used” i want to know why
(when i am changing forecast to LOCAL_FORECAST )
AND I REMOVED THE USE STRICT ALSO

#6

You are using forecast because that is the object passed to the function for you to destructure.

ya thanx, i got that but what is happening when i am using LOCAL_FORECAST

#8

The test is not wanting you to use it.

Well, it looks like it doesn’t want nested destructuring. It probably wants this:

const {max: maxOfTomorrow} = forecast.tomorrow;

But, it’s weird you’re getting that error because it says it wants it to be nested destructuring.
Also, your code passes for me. Are you using Chrome?

forecast is the function parameter, and you use that to make your function reusable. LOCAL_FORECAST is a global object, which is passed in the function as argument in the function call at the bottom of the code

YES i am using crome but when i am using .tomorrow at the end its saying error

#12

Well, that’s strange that the test doesn’t pass with your code. It’s not supposed to pass with mine actually.

Can you please post your latest code? You should not be using forecast.tomorrow.

The one in the top posts passes for me, I think it’s the latest.

#15

If it doesn’t pass, then what version of Chrome are you using? If it’s old (like 55 or something) try updating it.

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

function getMaxOfTmrw(forecast) {
“use strict”;
// change code below this line
const {tomorrow: {max: maxOfTomorrow}} = forecast; // change this line
// change code above this line
return maxOfTomorrow;
}

console.log(getMaxOfTmrw(LOCAL_FORECAST)); // should be 84.6

#17

that should work, I don’t know why it doesn’t

Can you share with us what browser and what version you are using? Also, can you post a screen shot of what the FCC console shows when you click Run Tests?

i am using CROME browser
and this is my code (currently working )
const LOCAL_FORECAST = {
today: { min: 72, max: 83 },
tomorrow: { min: 73.3, max: 84.6 }
};

function getMaxOfTmrw(forecast) {
“use strict”;
// change code below this line
const {tomorrow: {max: maxOfTomorrow}} = forecast; // i have a problem in understanding this line (why forecast and why not LOCAL_FORECAST
// change code above this line
return maxOfTomorrow;
}

console.log(getMaxOfTmrw(LOCAL_FORECAST)); // should be 84.6

and in console i am getting correct value .
i just want to know that when i am changing forecast to LOCAL_FORECAST whats happening in that line ehere i am using nested destructring …

Oh, so it’s solved, right?
