Default values when destructuring objects in JavaScript
You can also specify default values when
destructuring objects. In this case, unlike
array destructuring, any variable can be
optional - not necessarily from the end
of the array. Let's, for example, specify
a default value for the variable year:
let obj = {
month: 12,
day: 31,
};
let {year = 2025, month, day} = obj;
console.log(year); // shows 2025
console.log(month); // shows 1
console.log(day); // shows 31
In the following code, parts of the object are written to the corresponding variables:
let options = {
width: 400,
height: 500,
};
let color;
if (options.color !== undefined) {
color = options.color;
} else {
color = 'black';
}
let width = options.width;
let height = options.height;
Rework this code through destructuring according to the learned theory.
