Answer 1

In arrow function this keyword is inherited from the parent. I mean arrow function does not have its own this key word. Instead, you should use function expressions not the arrow functions. That is the reason!
I hope I'm understood!😉

there is a space missing from your print() func.
The bit after the colon :

console.log(this.name+": "+this.number);
