Closure to Protect Properties Within an Object from Being Modified Externally

JavaScript
1

Tell us what’s happening:
I tried and researched about this. I understood the concept but this is throwing the same errors. The tests cases that are not passing are " The weight property should be a private variable."

Your code so far


function Bird() {
  this.weight = 15;
  
  this.getWeight = function() {
    return this.weight;
  };
}

I didn’t start this section but as I can see maybe you want to use

let weight = 15;

also in the function dont’use return this.weight but return weight
