When you look at arrays and lists in programming, there are some important differences to know about:

1. Size:

   • Arrays have a set size.
   • Once you make an array, you can’t change how many items are in it.
   • Lists, on the other hand, can change size.
   • You can add or remove items whenever you need to.

2. Data Types:

   • Arrays usually hold items that are all the same type.
   • For example, they might only have numbers or only words.
   • Lists can hold different types of items all together.
   • You could have numbers, words, and even other lists in the same list!

3. Performance:

   • Arrays are quicker when you want to get or change an item.
   • Lists might take a bit longer to work with.
   • But lists are easier to use if you have a lot of data to keep track of.

So, when choosing between them, think about what you need!

• Use arrays when speed is important.
• Use lists when you want more flexibility!
