accessing prototype of javascript object

Question

I can access the prototype object of a javascript function using the .prototype but when I cannot use .prototype on a javascript object literal. Please let me know why is this behavior inconsistent.

var add = function (a, b) {     return a + b; };
var s={name:'Pradeep'}
console.log('Function\'s prototype >> '+add.prototype)
console.log('Object\'s prototype >> '+ s.prototype)

prototype is a property of a function not of obect... Having said that..You may want to do like this.. s.constructor.prototype — Rakesh_Kumar

The prototype property of a function is not the same thing as the function's prototype (inherited) methods.

myFunction.prototype is the object that will be used as the prototype of objects created using myFunction as a constructor (new myFunction()). See https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/new

What you're looking for is the __proto__ property, which accesses the inherited (prototype) methods of an object.

This is what I was looking for. Using the proto we can see the object's prototype.

The language specification uses [[Prototype]] to refer to the internal prototype property of objects that references the object's constructor's public prototype.
