new class vs new function prototype

class.js

function Foo1() {
}

Foo1.prototype.interact = function() {
    this.dispose = true
}

class Foo2 {
    interact() {
        this.dispose = true
    }
}

console.log('Foo1')
console.log(Object.getOwnPropertyDescriptor(Foo1, 'prototype'))
console.log(Object.getOwnPropertyDescriptor(Foo1.prototype, 'interact'))
console.log()
console.log('Foo2')
console.log(Object.getOwnPropertyDescriptor(Foo2, 'prototype'))
console.log(Object.getOwnPropertyDescriptor(Foo2.prototype, 'interact'))
