What is the difference between declaring a class using class constructor vs regular function

Question

Is there any difference between the two methods of setting up a class in javascript:

Example 1:

class Friend {
  constructor(name) {
    this.name = name;
  }
}

var friendOne = new Friend('John');

Example 2:

function Friend(name){
  this.name = name;
}

var friendOne = new Friend('John');

Both of these examples create:

// Friend.prototype
// {constructor: ƒ}

So my question is related to what approach is best for creating class based inheritance with Javascript?

Thanks

I think there is no obvious differences for them. compare with "Function" constructor, "class" just syntax sugar, more semantic.

Aaron, I see what your saying, but check out the link that @Ray Toal just posted... there are some other things aside from the "sugar" – jremi Mar 19 '18 at 02:00
That link mostly talk about differences of specification. – aaron.xiao Mar 21 '18 at 08:37
