A loop, as we know in common language, is circling the same path over and over again. In other words, if I am asked to fetch five ice creams from the ice cream store, and I can carry only one ice cream at a time, I will repeat the process of going to the ice cream shop to purchase ice cream five times. Correlating this with programming, if the same set of instructions need to be performed multiple times, then we put those instructions inside a loop.

A very basic loop is generally depicted as an iteration of a variable as many times as we want the instructions to be carried out.

Let's take an example:

Start the loop from one, until the loop has been repeated sixty times, adding a value of 1 to the loop:
Perform action

If you see the instructions being passed, there are three separate segments that are depicted in a loop:

1. Start the loop from one: This means that the loop should start with a value of one.
2. until the loop has been repeated sixty times: This means perform the same set of tasks until the loop has completed sixty turns of execution.
3. adding a value of 1 to the loop: This means that we dictate that after completion of each round of loop, increment the loop count by 1.

The result will be the same action performed sixty times, until the loop count reaches sixty. Additionally, a loop can used to iterate through multiple values stored in a variable irrespective of whether it is an integer, string, or any other data type.
