The JavaScript expression in question is "3 - -3".
In JavaScript, the minus sign (-) can be used both as a subtraction operator and as a unary negation operator.
When two minus signs are used together, the first one acts as a subtraction operator and the second one as a unary negation operator.
Therefore, the expression "3 - -3" is equivalent to "3 - (-3)", which simplifies to "3 + 3".
The result of "3 + 3" is "6", not "4".
Hence, the statement that the expression "3 - -3" returns the value "4" is False.
