Javascript – Calling an arrow function from another arrow function inside object literal notation

I want to use object literal notation to generate a namespace:

const featureGoogleAnalytics = {
  gTagId: 'G-XXXXXXX', // Your Google Analytics ID

...

  resetConsent: () => { // eslint-disable-line no-unused-vars
    localStorage.removeItem('googleAnalyticsConsent');
...
    return false;
  },


  /**
   * Initializes feature Google Analytics
   * Supposed to run after poageload, callback for $( () => { ... } );
   */
  init: () => { 
    this.resetConsent();
    ...
  },
};

Now the line

this.resetConsent();

Errors with

Uncaught TypeError: this.resetConsent is not a function

What did I miss? I assume the syntax of calling the resetConsent function is wrong, but I wasn’t able to Google it.

    The syntax is:

    featureGoogleAnalytics.resetConsent();

    From comments, don’t use an anonymous function wrapper in an Object definition.

    const featureGoogleAnalytics = {
  gTagId: 'G-XXXXXXX', // Your Google Analytics ID

...

  resetConsent: function() { // eslint-disable-line no-unused-vars
    localStorage.removeItem('googleAnalyticsConsent');
...
    return false;
  },


  /**
   * Initializes feature Google Analytics
   * Supposed to run after poageload, callback for $( () => { ... } );
   */
  init: function() { 
    this.resetConsent();
    ...
  },
};

    Alternatively:

    const featureGoogleAnalytics = {
  gTagId: 'G-XXXXXXX', // Your Google Analytics ID

...

  resetConsent() { // eslint-disable-line no-unused-vars
    localStorage.removeItem('googleAnalyticsConsent');
...
    return false;
  },


  /**
   * Initializes feature Google Analytics
   * Supposed to run after poageload, callback for $( () => { ... } );
   */
  init() { 
    this.resetConsent();
    ...
  },
};
