i have scenario multiple concrete classes extends multiple abstract classes. @ loss come clean structure, reduce number of files , avoid code repetition. the ask display various sensor values in different ways based on criteria. sensor values temperature, voltage, current etc can have anlaog widget, numeric label or combination of both. have 3 abstract classes 3 different kind of views. these 3 abstract classes implement method defines how view drawn. each sensor view extends 3 abstract classes , implements methods read sensor, perform engineering conversion , display sensor value. problem here code implemented concrete classes same no matter abstract class extends. canalogtempview , cdigitaltempview , ccustomtempview have same implementation extend different classes. this seems awkward. code repeated , number of source files increases factor of 3. missing simple here? there pattern problem this? can extends sensor view classes @ run time? actual code more complicated...

in ecmascript 6 typeof of classes is, according specification, 'function' . however according specification not allowed call object created via class syntax normal function call. in other words, must use new keyword otherwise typeerror thrown. typeerror: classes can’t function-called so without using try catch, ugly , destroy performance, how can check see if function came class syntax or function syntax? i think simplest way check if function es6 class check result of .tostring() method. according es2015 spec : the string representation must have syntax of functiondeclaration functionexpression, generatordeclaration, generatorexpression, classdeclaration, classexpression, arrowfunction, methoddefinition, or generatormethod depending upon actual characteristics of object so check function looks pretty simple: function isclass(func) { return typeof func === 'function' && /^class\s/.test(function.prototype.tostring.call(fu...
