javascript - Understanding prototype Property of function -

taken example if

var func = function(){} 

here func has property called prototype , can add custom methods following.

func.prototype.move = function(){ //do } 

as per understanding here prototype property of func default provided interpreter , not used delegate functionality, ie. there nothing like

func.move() 

applying same logic creating property of same function following

func.method = function(){ //do } 

now if create new object

var obj = new func(); 

here there obj.move() obj.method() wont there. if prototype property no magical advantages why behavior ?? in advance !

when use new prototype property of function used template internal [[prototype]] property of instance object. exposed in browsers __proto__, not confuse prototype again, regular property.

when attach property function directly, opposed prototype, using function namespace. since functions objects, can have arbitrary properties, , others built-in, prototype , name example. in effect creating similar static method, 1 doesn't depend on instance, doesn't use this.
