1.12 + ECMA Section: 11.9.3 The equals operator ( == )
1.13 + Description:
1.14 +
1.15 + The production EqualityExpression:
1.16 + EqualityExpression == RelationalExpression is evaluated as follows:
1.17 +
1.18 + 1. Evaluate EqualityExpression.
1.19 + 2. Call GetValue(Result(1)).
1.20 + 3. Evaluate RelationalExpression.
1.21 + 4. Call GetValue(Result(3)).
1.22 + 5. Perform the comparison Result(4) == Result(2). (See section 11.9.3)
1.23 + 6. Return Result(5).
