Use Destructuring Assignment to Assign Variables from Objects not passing

JavaScript
#1

Tell us what’s happening:

The code is returning 79 why is it not passing

Your code so far


const AVG_TEMPERATURES = {
  today: 77.5,
  tomorrow: 79
};

// console.log(today)
function getTempOfTmrw(avgTemperatures) {
  "use strict";
  // change code below this line
  const {today, tomorrow} = AVG_TEMPERATURES
  const tempOfTomorrow = tomorrow; // change this line
  // change code above this line
  return tempOfTomorrow;
}

console.log(getTempOfTmrw(AVG_TEMPERATURES)); // should be 79

Instead of giving away the answer, please try to give hints.

#4

Sorry, I’m new. I’ll give hints next time

#5

ok so what are the hints? now that your post was deleted I cant see anything

#6

It was not a hint. It was the working solution.

HINT: Think about a variable local to the getTempOfTmrw function’s scope that you can use which would be the same as using the global AVG_TEMPERATURES object.

#7

well whats wrong with
const {today, tomorrow} = AVG_TEMPERATURES
const tempOfTomorrow = tomorrow;

Im passing all these challenges but I still dont understand deconstructing

#8

I like to think of the following pattern when destructuring an object and need to create a variable with a different name than the original property name.

const { objectPropertyName: newVariableName } = objectName;
#9

The above line creates two variables (today and tomorrow).

Then the line above assigns the value of tomorrow to a variable named tempOfTomorrow.

If you use destructuring properly, you will not need that second line above.

const { tomorrow: tempOfTomorrow } = avgTemperatures;

#11

const {today, tomorrow} = AVG_TEMPERATURES isn’t the solution.

hint: Think about it in the way if they called the function with multiple objects:“AVG_TEMP1”, “AVG_TEMP2”, “AVG_TEMP3” and they wanted you to return tempOfTomorrow from all of them. That is what the problem is trying to ask.
