1.11 + File Name: 11.6.1-3.js
1.12 + ECMA Section: 11.6.1 The addition operator ( + )
1.13 + Description:
1.14 +
1.15 + The addition operator either performs string concatenation or numeric
1.16 + addition.
1.17 +
1.18 + The production AdditiveExpression : AdditiveExpression + MultiplicativeExpression
1.19 + is evaluated as follows:
1.20 +
1.21 + 1. Evaluate AdditiveExpression.
1.22 + 2. Call GetValue(Result(1)).
1.23 + 3. Evaluate MultiplicativeExpression.
1.24 + 4. Call GetValue(Result(3)).
1.25 + 5. Call ToPrimitive(Result(2)).
1.26 + 6. Call ToPrimitive(Result(4)).
1.27 + 7. If Type(Result(5)) is String or Type(Result(6)) is String, go to step 12.
1.28 + (Note that this step differs from step 3 in the algorithm for comparison
1.29 + for the relational operators in using or instead of and.)
1.30 + 8. Call ToNumber(Result(5)).
1.31 + 9. Call ToNumber(Result(6)).
1.32 + 10. Apply the addition operation to Result(8) and Result(9). See the discussion below (11.6.3).
1.33 + 11. Return Result(10).
1.34 + 12. Call ToString(Result(5)).
1.35 + 13. Call ToString(Result(6)).
1.36 + 14. Concatenate Result(12) followed by Result(13).
1.37 + 15. Return Result(14).
1.38 +
1.39 + Note that no hint is provided in the calls to ToPrimitive in steps 5 and 6.
1.40 + All native ECMAScript objects except Date objects handle the absence of a
1.41 + hint as if the hint Number were given; Date objects handle the absence of a
1.42 + hint as if the hint String were given. Host objects may handle the absence
1.43 + of a hint in some other manner.
1.44 +
1.45 + This test does only covers cases where the Additive or Mulplicative expression
1.46 + is a Date.
