*** Bug 187758 has been marked as a duplicate of this bug. *** |
Hello, The following code behaves strangely (inconsistent with other engines). class cc extends ( x = function () { console.log("Hi"); }) { }; In webkit, cc is defined normally and x is defined too. However, in V8 and Firefox, a ReferenceError is reported: ReferenceError: assignment to undeclared variable x BT group 2018.6.26
