javascript「include（）」函數不適用於nashorn

Question

我試圖在nashorn引擎上運行以下JavaScript代碼。

var fruits = ["Banana", "Orange", "Apple", "Mango"]; 
fruits.toString(); 
fruits.include("Orange"); 

但它提供了以下錯誤

"TypeError: fruits.include is not a function in at line number 3"

請告訴我如何解決這個問題。

Answer 1

不是include，而是includes。在末尾s。

var fruits = ["Banana", "Orange", "Apple", "Mango"]; 
 

 
console.log(fruits.includes("Orange"));
