  Static Semantics: Early Errors

    UnaryExpression : delete UnaryExpression

    It is a Syntax Error if the UnaryExpression is contained in strict mode code and the derived UnaryExpression is PrimaryExpression : IdentifierReference , MemberExpression : MemberExpression.PrivateName , or CallExpression : CallExpression.PrivateName .

    It is a Syntax Error if the derived UnaryExpression is PrimaryExpression : CoverParenthesizedExpressionAndArrowParameterList and CoverParenthesizedExpressionAndArrowParameterList ultimately derives a phrase that, if used in place of UnaryExpression, would produce a Syntax Error according to these rules. This rule is recursively applied.
