JavaScript Why is a Javascript Date from string different to the same date from Date object javascript date from string,javascript date from timestamp,javascript date

I just found an unexpected behavior where I have placed a timeStamp (Date) inside a hidden form field. When submitting the (update) form I made some checks on the document delta (because I only want to update the differences of the editing).

At that point I faced, that the unedited hidden Date field has been detected as being different.

I broke it down to the following reproduction code:

const date = new Date() // Mon Dec 10 2018 09:42:34 GMT+0100 (Timezone goes here)
const dateStr = date.toString()

console.log(date)                // "2018-12-10T08:42:34.388Z"
console.log(new Date(dateStr));  // "2018-12-10T08:42:34.000Z"
Answer:1

Because toString() converts the date to ISO 8601 with precision to the second.

The dates you are comparing differ by milliseconds.
