jquery - How to extend javascript class in ECMA5(IE11) ? -


ie11 not support ecma script 6. cannot use "class" syntax in ie11. then,how extend obj in ie11(ecma5) ?

//only ecma6+  // not work in ie11     class childobj extends google.maps.latlng {         constructor(child) {             super(number(child.lat), number(child.lng));             this.additionalprop = child;         }     } //ecma5  -> ????

i not know correct way define child class, e.g. childobj shown above ,in ecma5.

i think jquery $.extend not extending , merging properties. , how call parent class constructor in child class?

according mdn doc, do:

function childobj() {     google.maps.latlng.call(this); }  childobj.prototype = object.create(google.maps.latlng.prototype); childobj.prototype.constructor = rectangle;

but simpler solution if want use es6 components still have es5 code, use transpiler. example babel trick.
