|
|
1. Let exprRef be the result of evaluating Expression.
|
|
2. Let switchValue be ? GetValue(exprRef).
|
|
3. Let oldEnv be the running execution context's LexicalEnvironment.
|
|
4. Let blockEnv be NewDeclarativeEnvironment(oldEnv).
|
|
5. Perform BlockDeclarationInstantiation(CaseBlock, blockEnv).
|
|
6. Set the running execution context's LexicalEnvironment to blockEnv.
|
