What is Shakespeare's style of writing comedies and his technical side?

If you are asking about common comedic elements of Shakespearean
comedies, below are a couple.

1. Comedies end happily in contrast to
Shakespearean tragedies which conclude with death, normally the deaths of several
characters.

2. Almost all Shakespearean comedies include wedding
scenes. The Merchant of Venice has three marriages; Much Ado about
Nothing focuses on the relationships of several couples. Audience members will
recognize this element as a comedic technique. While Shakespearean tragedies often include
weddings (Romeo and Juliet and Othello are
examples), those weddings or marriages result in more conflict either
socially or domestically.

3. The comedies include a significant
amount of banter. Often it is between a couple who is romantically connected, but sometimes the
banter is between the lower class "clowns" of the plays.

While these
are not all of the elements common to Shakespearean comedies, they are the main
ones.
