ELI5: what is an array
// explanation
What is an array?
An array is like a special box that holds a bunch of items all in a row [1]. Think of it like a toy shelf where each spot holds one toy, and you can pick out any toy you want by knowing which spot it's in [1][3].
Why do we use arrays?
Arrays help us organize things so we can find them easily [1]. Instead of having one big messy pile, you put similar items in order, like arranging books on a shelf [3].
How do you use an array?
Each item in the array has a spot number (called an index), so if you want the third toy, you just ask for spot 3 [1][3]. You can put in as many items as you want—even just one item or a million items [3].
What can go in an array?
Arrays can hold different types of things like numbers, words, or even more complicated collections [4][5]. But usually, each array holds items that are all the same type, like all numbers or all words [5].
