How does Anne reveals her character through these diary entries?

As the diary is her property and prized possession, the readers remain in her head throughout the length of the book. In her diary she is precocious, intelligent, charming, and, even under the worst circumstances, funny. Over the course of the diary, she grows from a spoiled, somewhat naive young girl of thirteen to a self-aware young woman of fifteen. Although she has little political consciousness at the beginning of the diary, she grows to question anti-Semitism and the point of war. During her time in the annex, she suffers from boredom, despair, and the petty persecution of those around her. She also discovers a wealth of good qualities in herself. After the annex residents are discovered, she goes to the concentration camp at Belsen, in Germany, where she dies before her sixteenth birthday.
