Whenever the condition is true, the code inside the loop block will be executed:

It's worth knowing that this is quite a dangerous loop and you need to know how to use it. As a while loop does not create a control variable and is not iterating through the List, there is a possible scenario where a condition is always true. This will create an infinite loop-a loop that will go on forever. An infinite loop never finishes executing the loop block, and most certainly it will crash your program and even the Unity Editor.
