EqualityOperatorComparesObjectsValues
DRAFT

Misconception:

The equality operator == compares two objects’ values, returning true if they contain the same values for every property.

The equality operator compares two objects' values

The equality operator compares two objects' references

Consider the following code:

If the equality operator == compared objects looking at their values, it would conclude that obj1 is equal to obj2. But that is not what happens: the comparison is made between the two references contained in the two variables. As the two references refer to two distinct objects in memory, the comparison returns false.
