Bug 205498 – An issue of assignment expression

• Component: JavaScriptCore
• Status: NEW

According to ES10, the exception is described in static semantics and the exception should be thrown during parssing. I suspect it's a bug of javascriptCore.

    (e = n) = "object";
};

SyntaxError: Invalid left-hand side in assignment

Is this an issue? Looking forward to your reply! Thank you!
