Hello little one!
Have you ever played a game where you have to do something over and over again until you win? That's called iteration.
In computer world, Iteration is when the computer does a similar thing over and over again until it has finished the task. This can save time and effort.
For example, imagine you are a computer and your mom asked you to add up all the numbers from 1 to 10. Instead of adding them up one by one individually, you can use iteration by starting from 1 and adding 2, then adding 3, then adding 4 and so on, until you reach 10. This makes the job faster and easier.
That's what the word "iter" means when we talk about computer programming. It's like having a magic wand that tells the computer to do something repeatedly until it's been done!
