How can I create an array in AsyncStorage?

Question

I want to create a shopping cart. I use this code to save some data like username. Now I want to save product ID and Count in an array in AsyncStorage. (I use expo.)

How can I do that?

  _save_user = async () => {
  await SecureStore.setItemAsync('username', parseInt(this.state.Username).toString());
  };

Please tell me if you have some better idea.

you can try something like this:

var item1 = {itemCode:"10101010", quantity:"500", anythingElse:"this"};
var item2 = {itemCode:"10102020", quantity:"42", anythingElse:"is"};
var item3 = {itemCode:"10103030", quantity:"2", anythingElse:"something"};
var yourArray = [item1,item2,item3];

  _save_array = async () => {
     await SecureStore.setItemAsync('yourKey', JSON.stringify(yourArray));
  };

This way is not good. How can I save count of a product? And after that I want to show product and count in one page like cart page. How can I get that array? encode data to json is so good, but how can I save data like this: [username]=>{[productName]=> "Samsung" , [count]=> "5", [sum]=> "25800"}

@AlirezaDarvishi I just modify it, you can acces that object normally like yourArray[<ItemPosition>].itemCode / yourArray[<ItemPosition>].quantity / yourArray[<ItemPosition>].anythingElse ```
