Given a date, we’ll use the react-intl FormattedRelative component to render a date in a human readable format, such as “2 days ago”, in various languages.

We‘ll also see how to set the frequency of this component‘s rendering to make our app update the text in real-time.

                <
 
FormattedRelative 
                  value={new Date(review.date)}
                  style="numeric"
                  />

Since the FormattedRelative component udpate in real time, so you can also control the update interval:

                <FormattedRelative 
                  
 
value={new Date(review.date)}
                  updateInterval={1000}
                  style="numeric"
                  />

Notice that it will cause extra unecessary component render.
