English You've probably already used arrays countless of times in your programs. And you probably have a pretty good idea of how these things actually work. But did you ever stop and wonder what makes this data structure so popular and what actually goes on behind the scenes. For example how does inserting an element into an existing array work. What happens when an array grows in size and it simply gets too big. And what exactly is the phrase killer feature and why is it so popular when compared to other data structures like linked lists.
