How to save a scene while playing?

So i am making a game with a level editor but i would like to be able to save the scene with all the objects within it. I am not entirely sure this way of doing it is possible but i couldn’t find any confirmation or information on this method. If this is not possible how would code the saving of objects within a scene in JavaScript.

[Sorry for my english]
You want to save for later retrieve that information? I do not know what it is about your game, but you can save the name and position of each object using PlayerPrefs. Unity - Scripting API: PlayerPrefs
You can save every 5 minutes or checkpoints.
