By compressing the events of the story, Shakespeare was able to give it a breathlessness that makes us think of Romeo and Juliet being swept away on a tide of events.
Shakespeare compressed events in other stories as well. This is especially noticeable in the histories, where the events of twenty years are portrayed as if they happened in a couple of weeks or months. Shakespeare did this to keep the flow of the story going. But it is nowhere as pronounced as it is in Romeo and Juliet.

Friar Lawrence gave Juliet a potion that would put Juliet into a coma-like sleep for about two days straight. Everybody would think she was dead. Juliet's relatives would put her in a cellar (their family morgue) and Romeo and himself would be there waiting for her to wake up. Then Romeo and Juliet could live together in Mantua.

In Romeo and Juliet's days, chemists were typically referred to as alchemists. Alchemists were practitioners who combined elements of chemistry, philosophy, and mysticism in their search for ways to transform base metals into gold and to discover the elixir of life.
It confirms the story that Friar Lawrence tells the families. It tells what has happened over the four days that only Romeo, Juliet, Nurse, and Friar Lawrence knew. About how Romeo and Juliet fell in love and married, etc.
Capulet
"For you and I are past our dancing days" "It is the east, and Juliet is the Sun".
