我的HTML頁面似乎沒有運行我的JavaScript文件

我真的很陌生，因此對於基本問題非常抱歉。基本上我有這個HTML文件，當它被加載時應該運行我的文件script.js，我的朋友告訴我使用$（function（）{）來包含代碼，所以當我加載頁面時，它會運行整個腳本。然而，當我運行腳本時沒有任何事情發生，創建網頁應該在將對象數組加載到數組問題後，在div id = question_text中設置文本。我的HTML頁面似乎沒有運行我的JavaScript文件

這裏是我的HTML的頭，你可以看到我在的script.js

<!DOCTYPE html> 
<html> 

<head lang="en"> 
    <meta charset="UTF-8"> 
    <meta charset="utf-8"> 
    <meta http-equiv="X-UA-Compatible" content="IE=edge"> 
    <meta name="viewport" content="width=device-width, initial-scale=1"> 

    <link rel="stylesheet" href="../css/bootstrap-theme.min.css"> 
    <link rel="stylesheet" href="../css/bootstrap.min.css"> 
    <script src="../js/script.js"></script> 
    <title>Patient Questionnaire</title> 

</html>

加入這裏是我的JavaScript

$(function() { 

    questions = []; 
    count = 0; 
    addQuestions(); 
    createWebpage(); 

    function Question(questionText, possibleAnswers, chosenAnswer) { 
    this.questionText = questionText; 
    this.possibleAnswers = possibleAnswers; 
    this.chosenAnswer = chosenAnswer; 
    } 

    function addQuestions() { 
    var question1 = new Question(
     "Do you have or have you ever had high blood pressure?", ['Yes', 'No'], 
     "" 
    ); 

    var question2 = new Question(
     "Within the last year, have you had chest pain or pressure with activity such as walking or climbing stairs?", ['Yes', 'No'], 
     "" 
    ); 

    var question3 = new Question(
     "Do you currently take medication to prevent or reduce agnia (chest pain from the heart)?", ['Yes', 'No'], 
     "" 
    ); 

    var question4 = new Question(
     "Have you ever had a heart attack?" ['Yes', 'No'], 
     "" 
    ); 

    questions.push(question1); 
    questions.push(question2); 
    questions.push(question3); 
    questions.push(question4); 
    } 

    function createWebpage() { 
    document.getElementById("question_text").innerHTML = questions[1].questionText; 
    console.log("questions") 
    } 

});

我只用JavaScript的幾次之前，但通常我能夠通過獲取elementID並將其設置爲我想要的來實現它。

任何幫助將不勝感激！
