“Twilio Quest” challenge, any help would be appreciated, I dont know what I’m doing wrong,

Can’t seem to get a hang of this “Twilio Quest” Challenge.

Hey, I’ve been playing this game called “Twilio Quest” for the past week.
I just wanted to learn JavaScript, and I think it looked kinda neat.
The challenges served has been up and down in difficulty. But I’ve always managed to get around, until now.
Been reading through: JavaScript.info – Classes, MDN – Classes, JavaScript.info – Object literal notation and MDN – Object Initialization I tried alot of aproaches. But I really can’t seem to get a hang of this challenge.
Any help would be really appreciated. I just want to learn. Thanks in advance.
Heres what I’m trying to do:

class TargetingSolution {
  constructor(config) {
    // your code here
  }

  // your code here
}

// The following lines of code are not required for the solution, but can be
// used by you to test your solution.
const m = new TargetingSolution({
  x: 10,
  y: 15,
  z: 900
});

console.log(m.target()); // would print "(10, 15, 900)"

Answer

class TargetingSolution {
  constructor(config) {
    this.value = `(${config.x}, ${config.y}, ${config.z})`
    this.target = () => this.value;
  }
}

let m = new TargetingSolution({
  x: 10,
  y: 15,
  z: 900
});

console.log(m.target());
