how to use the parsejson function from date-fns in javascript

In order to parse a JSON string into a JavaScript date object using date-fns, you can use the parseJSON function from the library.

Here's an example:

index.tsx
import { parseJSON } from 'date-fns';

const jsonString = '{"year": 2021, "month": 11, "day": 21}';

const parsedDate = parseJSON(jsonString, new Date());

console.log(parsedDate);
// Output: Sun Nov 21 2021 00:00:00 GMT+0000 (Coordinated Universal Time)
255 chars
9 lines

In the example above, we first import the parseJSON function from date-fns. We then define a JSON string representing a date (in this case, November 21st, 2021). We call the parseJSON function with two arguments: the JSON string, and a fallback value (in this case, a new Date object).

The parseJSON function parses the JSON string and returns a JavaScript date object representing the date it contains. If the JSON string is invalid or cannot be parsed, the fallback value is returned instead.

Finally, we log the parsed date object to the console.
