/**
|

|
* A scope is a factory for creating and allocating
|
||||||
|
* {@link JsName}s. A JavaScript AST is
|
||||||
|
* built in terms of abstract name objects without worrying about obfuscation,
|
||||||
|
* keyword/identifier blacklisting, and so on.
|
||||||
|
* <p/>
|

|
* <p/>
|
||||||
|
* <p/>
|
||||||
|
* Scopes are associated with
|
||||||
|
* {@link JsFunction}s, but the two are
|
||||||
|
* not equivalent. Functions <i>have</i> scopes, but a scope does not
|
||||||
|
* necessarily have an associated Function. Examples of this include the
|
||||||
|
* {@link JsRootScope} and synthetic
|
||||||
|
* scopes that might be created by a client.
|
||||||
|
* <p/>
|
||||||
|
* <p/>
|
||||||
|
* <p/>
|
||||||
|
* Scopes can have parents to provide constraints when allocating actual
|
||||||
|
* identifiers for names. Specifically, names in child scopes are chosen such
|
||||||
|
* that they do not conflict with names in their parent scopes. The ultimate
|
||||||
|
* parent is usually the global scope (see
|
||||||
|
* {@link JsProgram#getRootScope()}),
|
||||||
|
* but parentless scopes are useful for managing names that are always accessed
|
||||||
|
* with a qualifier and could therefore never be confused with the global scope
|
||||||
|
* hierarchy.
