In this chapter, we cover using loops to perform repetitive tasks. The main types of loop are as follows:
for loopswhile loopsdo-while loopsfor loops repeat a block a set number of times. Use a for loop when you are sure how many iterations you want. A newer form of the for loop iterates over each item in a collection.
while loops execute a block while a given condition is true. When the condition becomes false, the while loop stops. Similarly, do-while loops execute a block and then check a condition. If true, the do-while loop runs the next iteration.
Use while loops if you are unsure how many iterations are required. For example, when searching through data to find a particular element, you normally want to stop when you find it.
Use a do-while loop if you always want to execute the block and only then check if another iteration is needed.
A for loop executes the same block...
