How was the US' strategy island hopping?

The U.S. strategy of island hopping during World War II involved bypassing heavily fortified Japanese islands and capturing strategically important ones to establish bases for further attacks. This approach aimed to conserve resources and minimize casualties while progressively moving closer to Japan. By capturing key islands such as Guadalcanal and Iwo Jima, the U.S. was able to disrupt Japanese supply lines and gain air superiority, ultimately leading to the successful invasion of the Japanese mainland. This strategy was pivotal in shifting the balance of power in the Pacific theater.
