prototype - JavaScript unable to access same object method after object.create(baseObject) -

-

i new javascript. have written code incorporating suggested answers. code block working in once scenario , not working in other scenario.

<script langugage="javascript">  var baseobject = {     name:"sunrise",     age:39,     printproperties:function(){         console.log("base class-> name:age:"+this.name+":"+this.age);     } } baseobject.printproperties(); console.log(baseobject);   /* code block works fine */  var derivedobject2=object.create(baseobject);     derivedobject2.education="m.c.a"     derivedobject2.printproperties=function(){           console.log("derived -> name:age:education:"+this.name+":"+this.age+":"+this.education);     }  derivedobject2.printproperties();  console.log(derivedobject2);   /* derivedobject.__proto__ = baseobject; derivedobject.printproperties(); // works fine */  /* code block not work  */  var derivedobject=object.create(baseobject,{       education:{value:"mca"},       //education:"mca",       printproperties:function(){           console.log("derived -> name:age:education:"+this.name+":"+this.age+":"+this.education);         return this;       } });  derivedobject.printproperties(); // getting error here,  console.log(derivedobject);   </script>

here error:

error:  uncaught typeerror: derivedobject.printproperties not function

use object.create() 

var baseobject = {     name:"sunrise",     age:39,     printproperties:function(){         console.log("name:age:"+this.name+":"+this.age);     } }

then

var derivedobject=object.create(baseobject);     derivedobject.education="m.c.a"     derivedobject.printproperties=function(){    console.log("name:age:education:"+this.name+":"+this.age+":"+this.education);         }  derivedobject.printproperties();

now derivedobject inherit properties of base object

edit can 

var derivedobject=object.create(baseobject,{               education:{value:"mca"},               printprop:function(){} });

object.create() abstracts of complexity associated prototypes

i've created components , helper methods using c++ , qt used in qml gui. of methods calculate gui elements (size, transformations, scene graph items creation). target arm 32 bit using opengl / eglfs render output. opengl using float , qml using real (defined double ). what should use in c++ do not lose precision? if use qreal ( double ) shouldn't lose precision. if git grep float in qtbase.git , can find out bit more: dist/changes-5.2.0-**************************************************************************** dist/changes-5.2.0-* important behavior changes * dist/changes-5.2.0-**************************************************************************** dist/changes-5.2.0- dist/changes-5.2.0- - qt compiled qreal typedef'ed double on dist/changes-5.2.0: platforms. qreal float on arm chipsets before. guarantees more dist/changes-5.2.0- consistent behavior between platforms qt supports, binary dist/chan...
