| michael@0 | 9 | ECMA Section: 11.9.2 The equals operator ( == ) |
| michael@0 | 10 | Description: |
| michael@0 | 11 | |
| michael@0 | 12 | The production EqualityExpression: |
| michael@0 | 13 | EqualityExpression == RelationalExpression is evaluated as follows: |
| michael@0 | 14 | |
| michael@0 | 15 | 1. Evaluate EqualityExpression. |
| michael@0 | 16 | 2. Call GetValue(Result(1)). |
| michael@0 | 17 | 3. Evaluate RelationalExpression. |
| michael@0 | 18 | 4. Call GetValue(Result(3)). |
| michael@0 | 19 | 5. Perform the comparison Result(4) == Result(2). (See section 11.9.3) |
| michael@0 | 20 | 6. Return Result(5). |
