Ruby do while.

It is due to the fact that in do while loop condition is written at the end of the code. First the code within the block is executed and then the. It isn t even necessary to understand what closures are or how they work in order to use these loops. It is just opposite of the while loop which runs until the given condition evaluates to false.

The until loop allows you to write code which is more readable and logical. Ruby has many features for making your code more expressive. The while statement is simple it executes code repeatedly as long as the condition is true. In a do while loop.

This chapter details all the loop statements supported by ruby. The ruby until loop runs until the given condition evaluates to true. Ruby provides the different types of loop to handle the condition based situation in. The statement does while loop in ruby allows developers to runs the same piece of code for the various time and executing code at least once for the first time or in a more clear way while loop in ruby is a way to run the same piece of code for as many time as needed for the situation along with executing once on the start of execution in any do while loop it.
