What are default values in JavaScript destructuring?

Can you explain what default values are in JavaScript destructuring?

Sure! Default values in JavaScript destructuring allow you to set a default value for a variable if the value unpacked from an object or array is undefined.

Can you give me an example of how to use default values in destructuring?

Of course! Here's an example:

const person = { name: 'Alice' };
const { name, age = 25 } = person;
console.log(age); // Output: 25

In this case, age will default to 25 since it's not defined in the person object.

What happens if the value is explicitly set to undefined?

If the value is explicitly set to undefined, the default value will not be used. For example:

const person = { name: 'Alice', age: undefined };
const { age = 25 } = person;
console.log(age); // Output: undefined
