Loops allow us to repeat the same steps of code as many times as we desire without having to type that code multiple times.

A danger of loops that that a poorly coded loop can last forever. So we always wish to include a condition in the loop that will cause it to stop. The a condition can be for the loop to run a specific number of times, or to keep running until a specified event occurs.

In the code below, the word while create the condition.

x = 0

while x < 5
  x = x +1
  puts x
end
