Why do programmers use loops? Can't we just write the code line by line?

Imagine you are selling chin-chin at the market. If you have 100 customers, would you want to shout the price individually 100 times, or would you rather use a megaphone to repeat the message?

Loops are our digital megaphones. They tell the computer: 'Do this same task until I tell you to stop.' It saves you from writing the same code over and over.

When I started coding in 2007, I realized that lazy programmers are often the best ones because they find ways to make the computer do the hard, repetitive work. Loops are the secret to that efficiency.
