Question
Which identity operator is used to check if two variables refer to the same object in memory?
- is
- ==
- ===
Solution
The identity operator used to check if two variables refer to the same object in memory in programming, specifically in JavaScript, is ===. This operator checks for both value and type equality, ensuring the two operands are identical in both value and their data type.
On the other hand, the == operator performs type coercion, meaning it will consider two values as equal even if they are of different types, as long as they can be coerced to the same type. Therefore, to determine if two variables reference the exact same object in memory, you should use the === operator.
In summary, the correct answer is ===.
