How did the strategy of "Island Hopping" enable the United States to turn the Japanese tide in the Pacific, and advance to within striking distance of the Japanese homeland?

Leapfrogging would allow the United States forces to reach Japan quickly and not expend the time, manpower, and supplies to capture every Japanese-held island on the way. It would give the Allies the advantage of surprise and keep the Japanese off balance. The overall leapfrogging strategy would involve two prongs. I hope this helps!
