ELI5: what is an array
// explanation
What is an array?
An array is like a special box or a spice rack that holds a bunch of things in a row [1][3]. Instead of having many separate boxes, you have one box with different spots inside, and each spot can hold one item [1].
Why do we use arrays?
Arrays help us keep lots of similar items organized in one place so we can find them easily [3][5]. If you have 10 numbers you need to remember, you can put them all in one array instead of creating 10 different storage spots [5].
How do you get something out of an array?
Each spot in the array has a number (called an index) so you can say "give me the thing in spot 1" or "give me the thing in spot 5" [1]. It's like a line of lockers where each locker has a number on it [3].
When would you use one?
You use arrays when you have a bunch of similar things you want to keep together, like a list of student names, test scores, or temperatures from each day [5].
