| 9 ECMA Section: 10.1.4 Scope Chain and Identifier Resolution | |
| 10 Description: | |
| 11 Every execution context has associated with it a scope chain. This is | |
| 12 logically a list of objects that are searched when binding an Identifier. | |
| 13 When control enters an execution context, the scope chain is created and | |
| 14 is populated with an initial set of objects, depending on the type of | |
| 15 code. When control leaves the execution context, the scope chain is | |
| 16 destroyed. | |
| 17 | |
| 18 During execution, the scope chain of the execution context is affected | |
| 19 only by WithStatement. When execution enters a with block, the object | |
| 20 specified in the with statement is added to the front of the scope chain. | |
| 21 When execution leaves a with block, whether normally or via a break or | |
| 22 continue statement, the object is removed from the scope chain. The object | |
| 23 being removed will always be the first object in the scope chain. | |
| 24 | |
| 25 During execution, the syntactic production PrimaryExpression : Identifier | |
| 26 is evaluated using the following algorithm: | |
| 27 | |
| 28 1. Get the next object in the scope chain. If there isn't one, go to step 5. | |
| 29 2. Call the [[HasProperty]] method of Result(l), passing the Identifier as | |
| 30 the property. | |
| 31 3. If Result(2) is true, return a value of type Reference whose base object | |
| 32 is Result(l) and whose property name is the Identifier. | |
| 33 4. Go to step 1. | |
| 34 5. Return a value of type Reference whose base object is null and whose | |
| 35 property name is the Identifier. | |
| 36 The result of binding an identifier is always a value of type Reference with | |
| 37 its member name component equal to the identifier string. | |
