Boolean toggle for class method

Question

I know there are similar questions but they do not provide the answer I am looking for. So what I'm trying to do is create a method that will toggle a boolean value.

class Example {
   constructor(name) {
     this._name = name;
     this._booleanExample = true;
  }
  toggleBoolean() {
    this._booleanExample = !this._booleanExample;
  }
}

I must not be doing something right though because when I call this method it does not toggle the boolean value.

const exampleOne = new Example('example');
exampleOne.toggleBoolean();
// the output remains true

Update:

Ok, so it must be something wrong with the site that I am using because I just recreated the example code inside VSC and everything works fine. I can assess and retrieve the booleanExample and also toggle it from true to false and vice versa.

I don't think you need to do this, but you could try using an arrow function for toggleBoolean to ensure that it's using the class-level this context.

class Example {
   constructor(name) {
     this._name = name;
     this._booleanExample = true;
  }
  toggleBoolean = () => {
    this._booleanExample = !this._booleanExample;
  }
}
