Controlling loops with break and continue

Having just discussed all the ways that we can control looping through code, it is important to know that sometimes we need to break out of a loop earlier than the condition of the loop specifies.

For such occasions, Kotlin has the break keyword. Here is break in action with a while loop:

var countDown = 10
while(countDown > 0){

  if(countDown == 5)break

  Log.i("countDown =","$countDown")
  countDown --
}

In the preceding code, the condition of the while loop should make the code repeatedly execute while the countDown variable is greater than zero. However, inside the while loop, there is an if expression that checks to see whether countDown is equal to 5. If it is equal to 5, the break statement is used. Also, ...
