Function serialize 

pub fn serialize<S: Serializer, T: JsCast>(
    val: &T,
    ser: S,
) -> Result<S::Ok, S::Error>

Serialize any JsCast value.

When used with the Serializer in serde_wasm_bindgen, this serializes the value by passing it through as a JsValue.

This function is compatible with the serde(serialize_with) derive annotation.
