What does iteration mean?

堕之旋律

While reading a book, I saw a sentence,
Use a foreach loop to iterate over the words in this array and write the words to the console,
What does this sentence mean?
But when I see this "iterative" word, I feel strange, I don't know what it means. .
Can someone make a solid sense of iteration? ? Thank you. .

"Iterative method", also known as "rolling method", is a process of recursively recalculating new values ​​from old values ​​of variables.

Iterative algorithm is a basic method for solving problems with computer. It takes advantage of the computer's fast computing speed and suitable for repetitive operations, allowing the computer to repeatedly execute a group of instructions (or certain steps), and each time the group of instructions (or these steps) is executed, the original value of the variable is used. Launch a new value for it.
