B.3.3.4 Changes to Block Static Semantics: Early Errors
|
||
|
|
|
||
|
|
For web browser compatibility, that rule is modified with the addition of the **highlighted** text:
|
||
|
|
|
||
|
|
Block: {StatementList}
|
||
|
|
|
||
|
|
It is a Syntax Error if the LexicallyDeclaredNames of StatementList contains any duplicate entries, **unless the source code matching this production is not strict mode code and the duplicate entries are only bound by FunctionDeclarations**.
