Hey,

Is there any way to convert datatype UInt8 to UInt16?

as a uint8 fits inside a uint16, the question is why?

- uint8 1 == uint16 1
- uint8 2 == uint16 2  
...
- uint8 255 == uint16 255

PS, there is no concept of uint8 in JavaScript. there is only [`number`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Data_structures#number_type) (and [BigInt](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Data_structures#bigint_type))
