组合数组中的元素

Question

感谢您阅读此问题。

  

让foodArray = [＆＃34; pasta＆＃34;，＆＃34; cheese＆＃34;，＆＃34; banana＆＃34;，＆＃34; water＆＃34;]

     

让expectOutput =＆＃34;意大利面;奶酪;香蕉;水＆＃34;

将foodArray转换为expectedOutput会有什么好方法？

谢谢。

Answer 1

let foodArray = ["pasta", "cheese", "banana", "water"]

let expectedOutput = "pasta;cheese;banana;water"
let actualOutput = join(";", foodArray)

let worked = expectedOutput == actualOutput

worked是true。
