Tell us what’s happening:
i am not able to understand reassignment. please help

Your code so far


const AVG_TEMPERATURES = {
  today: 77.5,
  tomorrow: 79
};
const {today:a,tomorrow:b}=AVG_TEMPERATURES
function getTempOfTmrw(avgTemperatures) {
  "use strict";
  // change code below this line
  const tempOfTomorrow = b; // change this line
  // change code above this line
  return tempOfTomorrow;
}

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

Two things:

1 - You have changed the function call, better avoid that and stick to what the lesson gives to you

console.log(getTempOfTmrw(AVG_TEMPERATURES));

2 - The lesson asks you to use destructuring with assignment inline inside the function, so don’t use global variables but leverage the function arguments and destructuring.

So this

 const tempOfTomorrow = b; // change this line

Should more likely looks something like [a hint, not the solution]

const { key: newAssignment } = objectPassedAsArg

Hope this helps :+1:
Btw you got the idea of how destricturing and assigning works, now it’s more a matter of making it compliant to FCC request
