What is the difference between const and let when working with objects in JavaScript?
In JavaScript, 'const' means the variable cannot be reassigned, but the object it points to can still be modified. 'let' allows both reassignment and modification.
Can you give me an example of using const with an object?
Sure! Here's an example:
const person = { name: 'Alice', age: 25 };
person.age = 26; // This is allowed
// person = {}; // This would throw an error
What happens if I try to reassign a const object?
If you try to reassign a const object, you'll get a TypeError. For example:
const person = { name: 'Alice' };
person = { name: 'Bob' }; // This will throw an error
Is it the same for arrays?
Yes, the same rules apply to arrays. You can modify the contents of a const array, but you cannot reassign it.
