object - Use of prototype in below example Javascript -

while going through concepts of prototype. saw below example stackoverflow - add new element existing object

var myobj = function(){     this.property = 'foo';     this.bar = function(){     } }  myobj.prototype.objprop = true; var newobj = new myobj(); 

my question use of "myobj.prototype.objprop = true;" above code snippet.

i beginner. referred other post similar this. couldn't make out.

any on appreciated. thanks.

prototype used having common values in similar objects. property objprop available objects not belong anyone.

when myobj.objprop, objprop searched inside myobj. if not found, property searched in __proto__.

also note if define property of same name inside object, myobj.objprop, add property in object , not override proto one

var myobj = function(){      this.property = 'foo';      this.bar = function(){      }  }    myobj.prototype.objprop = true;  var newobj = new myobj();    console.log(newobj);    console.log(newobj.objprop);
