Each time the question is asked, it is called an iteration. Loop will ask a question if the given answer is satisfied, then it will perform some actions, again it will ask a question, and this repeats until no further action required.

What are the different types of Loops provided by JavaScript? What are the loops in programming languages? Let's understand the idea of the loop in JavaScript by going through the following topics in this article: Now to handle these repetitive scenarios, all the programming languages provides the concept of ' loops'. The same is the concept with programming languages, where a particular piece of code needs to execute multiple times to achieve specific tasks. But for that, the user needs to repeat the same task on multiple pages to reach the final result. Now, the task that the user is performing is the same - searching the word. Suppose we consider a scenario that a user is searching for a word in a dictionary, for which the user needs to go through various pages of the glossary to do the same task.
