## Description



## Transcript

how do loops work in Ruby Ruby has lots of different built-in Loops we have while Loops until Loops do while Loops but the most common way that we iterate is typically using the each method on an enumerable but let&#39;s take a look at the basics so if we said while X is greater than zero we can print out X and then subtract one from X now we can run this with Ruby loops.rb and that will print out five four three two one now in many programming languages a for Loop is a common construct we have four Loops in Ruby but they&#39;re very rare we might say 4 x in one two five do and then we&#39;re going to print out X and now we can run that and we&#39;ll see something very similar now we&#39;re counting up one two three four five this one dot dot five is called a range in Ruby so we&#39;re iterating through all of the items in the range another interesting Loop in Ruby is just called Loop so we can say Loop do and now if we had a variable of I we can say I plus equals one and puts I break if I is equal to 10 and now we can run this code and it will print out one through ten Ruby also has a really interesting Loop called until so we can say I is zero and until I is equal to 10 I plus equals one puts I and you can run through this and again we get the numbers one through ten so we have while Loops for Loops until loops and just loops
