Ruby while loop. Ruby “next” Keyword In Ruby, the next keyword is used within a loop to pass over certain elements and skip to the following iteration. 3. Syntax collection.each do |variable| code end Rubyists prefer each. In Ruby, the recommended method to loop through stuff is using each command as shown below. If the condition is false the loop will continue to execute. We will be discussing two iterators here, each and collect. The following example explains how to loop through an array of numbers using each command in ruby. Well, in Ruby, we have all kinds of loops. We will cover while loops, do/while loops, and for loops.. A Simple Loop. To be clear, this code will not work in Ruby 1.8.6: a = 'hello, world' a.each_char { |c| puts c } This means that the codes inside the while loop will repeat if 'i' is less than or equal to 10. The each iterator returns all the elements of an array or a hash. You could say that we're iterating over each item in the array. Each with Index does what the name indicates: it iterates through each element in an array or hash, and extracts the element, as well as the index (the element’s place in the array) and will transform both the element and its index based on the code you have written. Ruby while loop. In Ruby, arrays and hashes can be termed collections. Instead of that people usually iterate over the elements of an array using the each method. This will become more useful when we get into collections.But we can use it with the Range (which is essentially a "collection" of integers) class that we're familiar with: The while loop will print out an array and use a variable to increment and keep track of what it is printing out.
