Я не могу прочитать JSON файл в Javascript и вернуть объект

Question

Я просмотрел несколько сообщений по этому вопросу, но не могу решить эту проблему. У меня был метод getData(), который возвращал объект со свойством под названием results. Это свойство содержало массив объектов следующим образом.

function getData() {
  return {
    "results": [{
        "title": "Terminator: Dark Fate",
        "poster_path": "/vqzNJRH4YyquRiWxCCOH0aXggHI.jpg",
        "genre_ids": [28,878],
        "shows": [0,1,2,3,4,5,6],
        "backdrop_path": "/a6cDxdwaQIFjSkXf7uskg78ZyTq.jpg",
        "overview": "More than two decades have passed since Sarah Connor prevented Judgment Day, changed the future, and re-wrote the fate of the human race. Dani Ramos is living a simple life in Mexico City with her brother and father when a highly advanced and deadly new Terminator – a Rev-9 – travels back through time to hunt and kill her. Dani's survival depends on her joining forces with two warriors: Grace, an enhanced super-soldier from the future, and a battle-hardened Sarah Connor. As the Rev-9 ruthlessly destroys everything and everyone in its path on the hunt for Dani, the three are led to a T-800 from Sarah’s past that may be their last best hope.",
        "runtime": "2h14m",
        "release_date": "2019-10-23"
    },{

        "title": "Fast & Furious Presents: Hobbs & Shaw",
        "poster_path": "/kvpNZAQow5es1tSY6XW2jAZuPPG.jpg",
        "genre_ids": [28,12,35],
        "shows": [0,3,4],
        "backdrop_path": "/qAhedRxRYWZAgZ8O8pHIl6QHdD7.jpg",
        "overview": "Ever since US Diplomatic Security Service Agent Hobbs and lawless outcast Shaw first faced off, they just have swapped smacks and bad words. But when cyber-genetically enhanced anarchist Brixton's ruthless actions threaten the future of humanity, both join forces to defeat him.",
        "runtime": "2h16m",
        "release_date": "2019-08-01"
    }]
  };

}

Я хочу перенести те же данные в файл .json и получить его через свойство results и сам этот метод. Файл с именем data.json, который я создал, является

 [{
        "title": "Terminator: ",
        "poster_path": "/vqzNJRH4YyquRiWxCCOH0aXggHI.jpg",
        "genre_ids": [28,878],
        "shows": [0,1,2,3,4,5,6],
        "backdrop_path": "/a6cDxdwaQIFjSkXf7uskg78ZyTq.jpg",
        "overview": "More than two decades have passed since Sarah Connor prevented Judgment Day, changed the future, and re-wrote the fate of the human race.

    }]

Я также включил свойство results в файл .json, но он выдал Uncaught SyntaxError: Unexpected token ':'

Как получить содержимое файла .json в Javascript? Я пытался использовать XMLHttpRequest также, но не повезло! Спасибо.

РЕДАКТИРОВАТЬ После использования XMLHttpRequest:

function fetchJSONFile(path, callback) {
    var httpRequest = new XMLHttpRequest();

    httpRequest.onreadystatechange = function() {
        if (httpRequest.readyState === 4) {
            if (httpRequest.status === 200) {
                var data = JSON.parse(httpRequest.responseText);
                if (callback) callback(data);
            }
        }
    };
    httpRequest.open('GET', path);
    httpRequest.send(); 
}

fetchJSONFile('data.json', function(data){
    /*
    Outputs error on console:
VM540:43 Uncaught SyntaxError: Unexpected token / in JSON at position 2617
    at JSON.parse (<anonymous>)
    at XMLHttpRequest.httpRequest.onreadystatechange (app.js:253)
   */
    console.log(data);
});
