How do I wrap an array with a string?

Js array can be made in JSON form using stringify.

var arr = [ "John", "Peter", "Sally", "Jane" ];
var myJSON = JSON.stringify(arr);

You can use the join function. Refer to Related lecture .

var a = ["abc", "def", "ghi"]
print(''.join(a))

I understand that if you are going to forward it to JSON.parse() in javascript, you should write dumps.

import json
mylist = ['a', 'b', 'c']
result = json.dumps(mylist)

Please forward this result to JSON.parse().
