Question

Whats the difference between (via prototypes)

var Todo = {};

Todo.prototype.name = "...";
Todo.prototype.hello = function() { ... }

Vs (variables & functions “outside” object)

var Todo = {}
Todo.name = "..."
Todo.hello = function() { ... }

Or even the below : variables & functions in object

var Todo = {
    name: "...",
    hello = function() { ... }
}

Answer 1

Think it like

A property or a function declared with prototype is an instance member of Todo.

A property or a function declared without prototype is a static member of Todo.
