How to explain prototype & class with 2 code examples

I have some questions with 2 codes, these are the 2 codes:, So what is prototype really? what is class really? what is the difference between prototype and class?

console.log(myFather)//why here will not show 'nationality: English'?
console.log(myFather.nationality)//why here do show ' English'?, console.log(myFather);//why here NOT show the method 'name: [function]'?
console.log( here do show'function'?
