What was an example of foil in

In literature, foil is a character that contrasts with another character in order to highlight specific qualities of the other character. For example, in Shakespeare's play "Hamlet," the character of Laertes serves as a foil to Hamlet. Laertes is quick to action, especially when his father, Polonius, is killed, whereas Hamlet is more deliberate and hesitant in his actions. This contrast highlights Hamlet's complexity and internal struggle. Foils can also be used to emphasize certain aspects of a character's personality or situation, or to provide a different perspective on events in the story.
