JavaScript Inheritance Standard function prototype
Example
Start by defining a Foo function that we'll use as a constructor.
function Foo (){}
By editing Foo.prototype, we can define properties and methods that will be shared by all instances of Foo.
Foo.prototype.bar = function() {
return 'I am bar';
};
We can then create an instance using the new keyword, and call the method.
var foo = new Foo();
console.log(foo.bar()); // logs `I am bar`
