I want to convert "['2022-03-24', '2022-03-25']" to javascript array data is from element.dataset
did const dateRange = JSON.stringify("['2022-03-24', '2022-03-25']")
JSON.parse(dateRange) returns ['2022-03-24', '2022-03-25'] which is a string and not a javaScript array.
I want to populate date range with flatpickr with object from my database so I'm passing the date html element via data attribute <input type="date" class="date-range" data-date="{{date_range}}" />
Try that, it would leave you with array of date strings, try to parse them to dates now (if you need).
someString.replace(/[',\]\[]/g, '').split(' ')
You can use the Function() object to create an instance of a function that will return an array. The second line below creates an anonymous function which is then immediately invoked via ().
const arrString = "['2022-03-24', '2022-03-25']";
const arr = (new Function(`return ${arrString}`))();
console.log( arr );
DEMO
const arrString = "['2022-03-24', '2022-03-25']";
const arr = (new Function(`return ${arrString}`))();
console.log( arr );
