The document discusses JavaScript's prototype property and object-oriented programming. It explains that in JavaScript, objects inherit properties and methods from a prototype object, allowing for code reuse and extension of functionality. The prototype is an object that is shared among objects created from the same constructor function. All objects in JavaScript inherit from the Object prototype by default.
