Transforming a 10-digit Timestamp into a Readable Date

Deciphering a 10-digit timestamp can be perplexing. Encountered this value in a JSON API response instead of the expected date format. Initially puzzled on how to convert it for UI display, I later discovered that these 10-digit timestamps represent seconds.

Enough with the history lesson, now, how can we make it useful in JavaScript?

    // Timestamp
    const ts = 1504095567183

    // Native
    new Date(ts)

    // Moment.js
    moment(ts)

    // day.js
    dayjs.unix(ts)
