Converting a String to Object in Javascript

Question

How can I convert a string to object? that is my data :

  "({"test1":[{"test2":55,"test":"15.06"},
   {"test3":55,"test4":"15.08"}]})"

Apply ``eval(...)`` on it. May be also understand the evils of eval. — KalEl, May 01 '17 at 22:08
I see that in that chain you have two objects will always be like this or will it be one? If it's an object you can use `JSON.parse` — Alan Olivares, May 01 '17 at 22:12

If you remove the surrounding parentheses, you will get a JSON string, which can be converted to an object using JSON.parse():

var s = '({"test1":[{"test2":55,"test":"15.06"}, {"test3":55,"test4":"15.08"}]})',
    j = s.replace(/^\((.+)\)$/, '$1'),  //remove surrounding parentheses
    o = JSON.parse(j);

console.log(o);

`eval()` can be dangerous if you don't have control over the string. Otherwise, it should work fine. See http://stackoverflow.com/questions/86513/why-is-using-the-javascript-eval-function-a-bad-idea – Rick Hitchcock May 01 '17 at 22:26
