TypeError: Cannot read properties of undefined (reading 'a')

I was trying classes and the this keyword in Javascript,and I wrote this code:

class p{
  constructor(p,a){
      p = p.p;
      a = p.a;
  };
};
const c = new p(p="1st aspect",a="2nd aspect");
console.log(this.c);

And I got this Error:

Cannot read properties of undefined (reading 'a')

I don’t know whether this is compatible with classes or whether I passed in the wrong arguments,can someone help me there?

>Solution :

The syntax for creating a class is wrong. You don’t need to pass the parameter names. Just use

const c = new p("1st aspect","2nd aspect");

And it is not good practice to use lowercased frist letter as class name. Use P instead of p. And this.c is wrong. Just print

console.log(c);
