Elizabeth is an experiential learner who grows over the course of the novel and, in the process, overcomes her prejudice against Mr. Darcy.
As the novel opens, Elizabeth overhears the proud, wealthy, high-status Mr. Darcy say that she is not attractive enough to tempt him to dance with her. Part of the reason women relate to this novel is that anyone else would be likely to have a similar reaction: Elizabeth laughs it off to her friends but inside develops a deep prejudice against Darcy as an arrogant jerk. After all, really, how much would it have taken to dance with her? Who was he is to think he was so superior?
Early in the novel, her prejudice receives confirmation through Wickham, who complains at length that Darcy has wronged him. Elizabeth, suffering from confirmation bias, is eager to believe anything that shows she is right in hating Darcy.
However, as Elizabeth gains more experience, she comes to question her initial prejudice. This first happens after she rejects Darcy's arrogant marriage proposal in a burst of fury. He writes her a letter explaining his side of the Wickham story. This causes Elizabeth to reflect that perhaps she allowed her prejudice to blind her to the idea that Wickham might not have been truthful.
Later, when visiting and admiring the taste, wealth, and order of Pemberley, Elizabeth further begins to reconsider whether she was too hasty in developing a prejudice against Darcy. She comes to think it would be something to be mistress of his estate. She learns to respect Darcy when he saves Lydia.
By the end of the novel, Elizabeth is fully able to confess to Darcy that she misjudged him and allowed this prejudice to influence her unduly. A more mature person, she has learned from her experience not to jump to hasty conclusions and let prejudices consume her. She demonstrates how she overcame her prejudice by marrying Darcy, the man she once despised.
