ES6: Use Destructuring Assignment to Assign Variables from Nested Objects - pulkitbhutani/My-FreeCodeCamp-Code GitHub Wiki

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.

Use destructuring assignment to obtain max of forecast.tomorrow and assign it to maxOfTomorrow.

The destructuring assignment syntax is a JavaScript expression that makes it possible to unpack values from arrays, or properties from objects, into distinct variables.

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
