| ECMA Section: 11.2.1 Property Accessors |
| Description: |
| |
| Properties are accessed by name, using either the dot notation: |
| MemberExpression . Identifier |
| CallExpression . Identifier |
| |
| or the bracket notation: MemberExpression [ Expression ] |
| CallExpression [ Expression ] |
| |
| The dot notation is explained by the following syntactic conversion: |
| MemberExpression . Identifier |
| is identical in its behavior to |
| MemberExpression [ <identifier-string> ] |
| and similarly |
| CallExpression . Identifier |
| is identical in its behavior to |
| CallExpression [ <identifier-string> ] |
| where <identifier-string> is a string literal containing the same sequence |
| of characters as the Identifier. |
| |
| The production MemberExpression : MemberExpression [ Expression ] is |
| evaluated as follows: |
| |
| 1. Evaluate MemberExpression. |
| 2. Call GetValue(Result(1)). |
| 3. Evaluate Expression. |
| 4. Call GetValue(Result(3)). |
| 5. Call ToObject(Result(2)). |
| 6. Call ToString(Result(4)). |
| 7. Return a value of type Reference whose base object is Result(5) and |
| whose property name is Result(6). |
| |
| The production CallExpression : CallExpression [ Expression ] is evaluated |
| in exactly the same manner, except that the contained CallExpression is |
| evaluated in step 1. |
