JavaScript · Junior · Question 51 of 75

Does this code throw an error?

const user = { name: "Ann" };
user.name = "Bob";

✓Correct answer: No - const forbids reassigning the variable, not changing the object it points to
2Yes - const objects are frozen
3Yes - but only in strict mode

Explanation

user = {} would throw a TypeError, but mutating properties is allowed. To make the object itself read-only, use Object.freeze (shallowly).
