Loops are used anytime you want to execute a repeated series of actions, usually as an iterative process: looping through every element in an array, for example.

JavaScript offers several different kinds of loop structures, depending on the task at hand. Most coders start with a basic for loop, which is why it is placed first in this reading list; more advanced loop structures follow, with others (such as forEach) to come shortly.
