Split a string into a list of strings

Question

I have an input Json string like this:

var x= "[{\"name\":\"ahmed\",\"age\":\"26\"}, 
{\"name\":\"Sam\",\"age\":\"25\"}]"

I want to split it to a list of strings from{ to } as follows without removing a delimiter

var list;
 list[0]= {\"name\":\"ahmed\",\"age\":\"26\"}
 list[1]= {\"name\":\"Sam\",\"age\":\"25\"}

using the split method removes the delimiter and does not yield the correct format

x= x.replace(/\[\/]/g, '/'); //to remove [ and ]
x= x.replace(  /},/ ,'}\n' ); // does not split the string to list of strings
list = x; // type mismatch error since x is a string and list is array

As commented above by Teemu, using JSON.parse is the safe and correct way to parse json.

const x = "[{\"name\":\"ahmed\",\"age\":\"26\"},{\"name\":\"Sam\",\"age\":\"25\"}]";

console.log(JSON.parse(x));

You can parse it to JSON first then use map to make list out of it.

var parsedX = JSON.parse(x);
var list = parsedX.map(x => JSON.stringify(x).replace(/"/g,'\\"'));

You could use following code to achieve desired result with this particular type of json:

var str = "[{\"name\":\"ahmed\",\"age\":\"26\"}, {\"name\":\"Sam\",\"age\":\"25\"}]";
var list = str.match(/[{][^{}]*[}]/gm);

alert(list)
