Javascript Function With Prototype Within Parent Function Prototype

Is this even possible? function foo() { // do stuff } foo.prototype = { // stuff... bar: function() { // do some things with this, where this refers to foo

Solution 1:

No. You'd need to use

functionbar() {...}
bar.prototype = {...};
functionfoo() {...}
foo.prototype.bar = bar;

Although this won't work. There is no reason to put the bar constructor on foos prototype, because when instantiating bar objects by using new ((new foo()).bar)(), there will be no reference to the foo instance. You could equally use new foo.prototype.bar().
