title: Use Destructuring Assignment to Assign Variables from Nested Objects
challengeType: 1
---
## Description
We can similarly destructure nested objects into variables.
Consider the following code:
const a = {
start: { x: 5, y: 6},
end: { x: 6, y: -9 }
};
const { start : { x: startX, y: startY }} = a;
console.log(startX, startY); // 5, 6
In the example above, the variable start is assigned the value of a.start, which is also an object.
## Instructions
Use destructuring assignment to obtain max of forecast.tomorrow and assign it to maxOfTomorrow.
## Tests
```yml
tests:
- text: maxOfTomorrow equals 84.6
testString: 'assert(getMaxOfTmrw(LOCAL_FORECAST) === 84.6, "maxOfTomorrow equals 84.6");'
- text: nested destructuring was used
testString: 'getUserInput => assert(getUserInput("index").match(/\{\s*tomorrow\s*:\s*\{\s*max\s*:\s*maxOfTomorrow\s*\}\s*\}\s*=\s*forecast/g),"nested destructuring was used");'
```
## Challenge Seed
```js
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 maxOfTomorrow = undefined; // change this line
// change code above this line
return maxOfTomorrow;
}
console.log(getMaxOfTmrw(LOCAL_FORECAST)); // should be 84.6
```
