JavaScript Constructor Functions, hereafter referred to as constructors, are called with the new keyword and return (yep) a new object. A constructor looks something like this:

function Plant(kind) { /*

Initialize object */ }

And making an instance with the constructor:

var bush = new Plant(“bush”);

What the instance has access to (its API) defines whether a constructor property is public or private, and these can be defined in scope or out of scope.

function Plant() {

// In scope of the constructor's execution context

}

// Out of its scope
