- File Name: 11.9.1.js
- ECMA Section: 11.9.1 The equals operator ( == )
- Description:
-
- The production EqualityExpression:
- EqualityExpression == RelationalExpression is evaluated as follows:
-
- 1. Evaluate EqualityExpression.
- 2. Call GetValue(Result(1)).
- 3. Evaluate RelationalExpression.
- 4. Call GetValue(Result(3)).
- 5. Perform the comparison Result(4) == Result(2). (See section 11.9.3)
- 6. Return Result(5).
