As discussed earlier, Go does not offer the while keyword for writing while loops, but it allows you to use a for loop instead of a while loop. This section will present two examples where a for loop does the job of a while loop.

The following is the typical case where you want to write something like while(condition):

for { 
} 

It is the job of the developer to use the break keyword to exit this for loop!

However, the for loop can also emulate a do...while loop that are found in other programming languages. As an example, the following Go code is equivalent to a do...while(anExpression) loop:

for ok := true; ok; ok = anExpression { 
} 

As soon as the ok variable reaches the false value, the for loop will terminate.
