In a world obsessed with speed, we often overlook the silent helpers working tirelessly to make our digital lives more efficient. One such hero is a concept known as 'caching'. Now, you might wonder, 'What exactly is caching and why should I care?' Imagine walking into a library and, instead of having to search through the vast maze of bookshelves for your favorite author's latest novel, you find it neatly placed on a small table just by the entrance. That's similar to what caching does for our digital experiences.
