    var aux = { startItem: 2 }
var jsonStr = aux.replace(/(w+:)|(w+ :)/g, function(matchedStr) {
                      return '"' + matchedStr.substring(0, matchedStr.length - 1) + '":';
});
var obj = JSON.parse(jsonStr);
console.log(obj);

    This will work.

    Use JSON.stringify()

    Example run in chrome console:

    > JSON.stringify({ startItem: 2 })
  '{"startItem":2}'

    And JSON.parse the other way :

    > JSON.parse('{"startItem":2}')
  {startItem: 2}

    Edit:

    So you have a string ‘{ startItem: 2 }’. And you dont want to use eval, then you can use Function:

    > const transform = (value) => Function(`return ${value}`)()
> transform('{ startItem: 2}')
  {startItem: 2}

    And then you can JSON.stringify this one.
