Answer 2

In 1 case arrow functions are used. They do not have their own this, inheriting from the parent. For example:

// Пусть this - [object MyObject]
function log() {
    console.log(this);
};

var obj = new MyObject2();
obj.on("ready", () => log()); // [object MyObject];

In case 2, a function that has not yet been called is simply passed. And when it is called, another this is used.

// Пусть this - [object MyObject]
function log() {
    console.log(this);
};

var obj = new MyObject2();
obj.on("ready", log); // [object MyObject2];

Everything is very simple, you just need to read about classes. They have properties and functions. So when we use this, we indicate that we want to access a property or method of an instance of this class. Try to look at your code in more detail. If you go upstairs, you will see that the msg property is declared at the top, or declared in the parent class from which your class inherits.
