How does the author use foreshadowing in Golden Boy?

In the play, Odets makes use of some very overt foreshadowing techniques which plant clues that tip the reader off to what may happen in the future. The foreshadowing shows up in reference to Joe's death.

In the very first scene, Moody talks to Lorna about "Cy Webster who got himself killed in a big, red Stutz." The reference to the dead boxer on its own may not let the reader know that Joe is going to die, but it is backed up by several other references. In the fourth scene of the first act, Joe goes on at length to Lorna about how he wants a fast car, saying that: "Those cars are poison in my blood," and "Gee, I like to stroke that gas!" In addition, there are several other references to fast cars, speeding, and the danger that is involved, most of which are said by Joe's managers. Says Moody: "But you and your speeding worries me!" As a result of these and other references, Joe's death by an automobile accident in his fast car should come as no surprise since the thought of that ending has been built up in the reader's mind from the beginning of the play.
