Play Framework:如何将List转换为JsArray

Question

鉴于以下List......

val list = List("one", "one", "two", "two", "three", "three")

...我怎么把它转换成JsArray这样的？

["one", "two", "three"]

如您所见,我还需要删除重复项.

根据文档应该是这样的:

import play.api.libs.json._

Json.toJson(List("one", "one", "two", "two", "three", "three").distinct)
