Question 5

Spot the false statement about primitive value immutability.

  1. A string operation cannot alter the original string value
  2. A number value cannot be changed internally
  3. A variable can later hold a different primitive value
  4. Reassigning a variable mutates its old primitive valueCorrect answer

Explanation

A variable may be assigned a different primitive value, but that operation changes the binding rather than the original primitive. Therefore the claim that reassignment mutates the old value confuses rebinding with mutation.
