テーブルの特定のセルにJSONデータを表示

私はまったく新しいJavaScriptです。 JSONをループして、特定のセルにデータを送信する必要がある生徒のタイムテーブルにデータを表示しようとしています。私の現在のコードはうまく動作しますが、はっきりとした控えめな外観になります。私は、 "if文"のロードを使用する代わりに、これを行うより効率的な方法があるかどうかを知りたいだけです。ヘルプははるかにテーブルの特定のセルにJSONデータを表示

function displayJSON() { 
    for (var parkName in parksListJSON) { 
     var park = parksListJSON[parkName]; 
     console.log(park); 
    } 

    var schedule = parksListJSON.schedule; 

    for (var i = 0; i < schedule.length; i++){ 
     var schedule = parksListJSON.schedule; 
     var moduleCode = schedule[i].module; 
     var session = schedule[i].sessionType; 

     if (!parksListJSON.schedule[i].allocatedTime) { 
      var lecCode = schedule[i].module; 
      var type = schedule[i].sessionType; 
      var lecLocation = schedule[i].location; 
      var fred = ('<td class="something"> ' + lecCode + ',<br> ' + type + '<br> ' + lecLocation + ' ' + '</td>'); 

      if (moduleCode == "uh6com1051"){ 
       document.querySelector("#thurs .s15").innerHTML=fred 
      } 

      if (moduleCode == "uh6com1099"){ 
       document.querySelector("#fri .s12").innerHTML=fred 
      } 

      if (moduleCode == "uh6com1063"){ 
       document.querySelector("#tues .s12").innerHTML=fred 
      } 
     }else 
     { 
      var groupName = schedule[i].allocatedTime.group; 
      var locations=schedule[i].allocatedTime.location; 
      var array = [moduleCode,session,locations,groupName]; 
      var fred = ('<td class="something"> ' + array[0] +',<br> '+ array[1]+',<br> ' + array[2] +', ' + array[3] + ' ' + '</td>'); 

      if (moduleCode == "uh6com1051"){ 
       if (session == "tutorial"){ 
        document.querySelector("#weds .s9").innerHTML=fred; 
       } 
      } 
      if (moduleCode == "uh6com1051"){ 
       if (session == "lab"){ 
        document.querySelector("#mon .s11").innerHTML=fred; 
       } 
      } 
      if (moduleCode == "uh6com1063"){ 
       if (session == "lab"){ 
        document.querySelector("#tues .s11").innerHTML=fred; 
       } 
      } 
      if (moduleCode == "uh6com1063"){ 
       if (session == "tutorial"){ 
        document.querySelector("#mon .s13").innerHTML=fred; 
       } 
      } 
      if (moduleCode == "uh6com1099"){ 
       if (session == "tutorial"){  
        document.querySelector("#weds .s11").innerHTML=fred; 
       }
