Serialize, Save and Load using Javascript

Hi, i’m sorry if i’m asking something that’s probably already been answered before, but i did my research & i can’t find anything regardless of how to serialize, save & load using javascript, not at least something that’s not 6 years old & probably off-date.
Can someone point me up where too look? :I


For saving a game, it is best to use C#, because it has better compatibility. Take a look at this video

You can use PlayerPrefs and get PlayerPrefsPlus.

With dedication you can even save and load GameObjects. I have all of my structures where they save and load their GameObjects, position, rotation, health, on/off state, ect.
