How does Harper Lee use the character of Scout tell the story of 'To Kill A Mockingbird?

'so i have a few points. for example, the use of themes of prejudice and how scout is judged a girl. and also Harper Lee chose scout to be the narrator because her perspective of everything is different. but i need quotes and evidence to back this up. please help me. can you give me a few quotes from the book maybe that relate to this? and also are there any points were the author uses irony, or foreshadowing or any other devices throughout the novel? PLEASE HELP ME GUYS
