@YuHayate you can shove whatever extra properties you want into a Sprite using the `sprite.data` property.

For example:

```auto
console.log(sprite.data.name) // prints "undefined"

sprite.data.name = "josephine"

console.log(sprite.data.name) // prints "josephine"
console.log(sprite.data["name"]) // prints "josephine"

```

Just be aware that the `sprite.data` property has the `any` type so you need to be careful when accessing properties off of it. The compiler won’t catch any spelling or type errors

```auto
let list: any[] = []
console.log(list.name)
// returns list

```

Ah, you mean getting the name of a variable as a string? We don’t support that.

If you’re just trying to check the type of something at runtime, then `instanceof` is good for that. For example:

```auto
function printType(arg: any) {
    if (arg instanceof Sprite) {
        console.log("Sprite")
    }
    else if (arg instanceof Array) {
        console.log("Array")
    }
    else {
        console.log("Unknown")
    }
}

```

</div>

That code will break. I’m note sure what you’re trying to do here exactly either…  
Like @richard said, to assign a name to a sprite, do `sprite.data.name = "name"`

To retrieve it just grab `sprite.data.name` or `sprite.data["name"]`

it was an example, what i want is to get the name of the variable like the text we use to declare set modify the variable  
like if we declare a variable like `let NameOfSprite = "anything"`  
i want a way to get the name of the sprite (in this case NameOfSprite) and return it as a string

That’s unfortunately not possible. Could you provide a use-case scenario where you would need this?

well if i want to use `throw ""` with a function a make to replace all \<‘number’\> to a string in a array at index ‘number’, i wanted to get a sprite name to make the error look more clear

You can just write “list”, it will be apparent which variable it’s referring to because it will highlight the line/block in question

@YuHayate do you mean a specific javascript library?

extensions are themselves libraries. however, if you’re trying to use some 3rd party non-makecode library it will really depend on the implementation as to whether it will work or not. most likely it will not work unless the library is very very simple.

</div>

hey @richard! i was making a extension and i tried to make a total run time function using `settings.`  
but instead of keeping track of the total time like in [This](https://makecode.com/_XrHbrMep97Tm), so in that example i use the better settings extension [here](https://github.com/S0m3randomguy/BetterSettings).  
but if i use `setting.` from the javascript editor it just makes makecode not work? it just makes the editors not work or take 5 minutes to load

the code im using in my extension

```auto
settings.writeNumber("StartRunTime", settings.readNumber("TotalRunTime"))
let TotalRunTime = 0

game.onUpdate(function() {
        TotalRunTime = game.runtime() + settings.readNumber("StartRunTime");
        settings.writeNumber("TotalRunTime", TotalRunTime);
})

```
