File Name: 11.2.1-4-n.js
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.
