将具有特殊字符的数组转换为字符串

Question

i have the below array:

let arr= ["5,5", "Orange", "6,1"];

Every item in that arr is random string and contains any character ( "," , ";" ,...")

For some reasons, i have to convert arr to string.

I used let s = arr.toString() and got the string: s= "5,5,Orange,6,1"

The problem is: I have to convert that string back to the array without reusing arr and losing the format. If i use string.split(",") , the result is ["5", "5", "Orange", "6", "1"] instead of ["5,5", "Orange", "6,1"]

i know toString() is the same to join array with "," , but if i use arr.join() with other character then split() , it seems silly because item in arr is random and can contain any character.

Thanks a lot!

This is what JSon is for.

 let arr= ["5,5", "Orange", "6,1"]; let arrStr = JSON.stringify(arr); console.log('arrStr: ', arrStr, 'as string'); let newArr = JSON.parse(arrStr); console.log('newArr:', newArr);
