C# line into Javascript help

I downloaded this save and loading thing from the asset store and I have made a script for loading and saving but id prefer it to be in javascript since I don't know anything about c#. I can make it all in javascript but the line where it saves and loads im not sure how to do it in java.

c# code

 using UnityEngine;
 using System.Collections;
 
 public class SaveMenu : MonoBehaviour {
 
     void OnGUI()
     {
 
         if(GUI.Button(new Rect(10, 50, 150, 25), "Save"))
         {
             transform.GetComponent<AdvancedSaveSystem_SaveGO>().SaveGameObjects(1);
         }
 
         if(GUI.Button(new Rect(10, 80, 150, 25), "Load"))
         {
             transform.GetComponent<AdvancedSaveSystem_LoadGO>().RefreshGameObjects(1);
         }
     }
 }
