What do you think of the ending? How does it help to develop the message of the text?

In J.D. Salinger's book the Catcher in the Rye, the ending in my point of view is seen as a reveal of Holden's maturity as he wants to branch off and live with himself, and also as the reveal of who and what the Catcher in the Rye is, which I enjoy. Overall, I like the end of the story and I feel like it demonstrates the true meaning of the title and what was meant for Holden to do later on in his life.

At the end of the book when Holden decides to go off on his own, and live by himself, this develops a message of this text because it finally shows the coming of Holden's maturity and not a foolish and childish mindset. I think that it shows juxtaposition from the start of the book to now.
Secondly, I think that near the ending, when it revealed who and what the Catcher in the Rye was, it showed a huge turning point to the text and helped the reader understand why the book is named The Catcher in the Rye. This develops the message of the text because it reveals who Holden is, why has that name upon him and indicates his protection for innocence, especially children.
