It is implemented in the <strong>Ruby programming language, a back-end language.<\/strong>&nbsp;<\/p>\n\n\n\n<p>Ruby by itself was created in 1993 by Yukihiro Matsumoto and is a flexible and precise language. It allows for the possibility of organizing written code in a more efficient way. The Ruby syntax is based on blocks of code, so errors are avoided when changing the instruction line.&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" data-src=\"https:\/\/lh3.googleusercontent.com\/blnaTPu-GW8iyppeIDdu4JHxcE6PHG4lJVSD2V1xwUzfLBNMyFLlFinBKEmhRF8mqhddS2beH40giwQFtQrKFZuGfLyxctjMPqCxS4V8AzENAeQ5qSOfwhXwzFOE-egOj573rqoY\" alt=\"Ruby on Rails Developer - Role Overview\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" class=\"lazyload\" \/><figcaption class=\"wp-element-caption\">Ruby on Rails Developer &#8211; Role Overview<\/figcaption><\/figure>\n\n\n\n<p>The Ruby language, however, did not rise to international fame until 15 years later, in 2008, five years after being combined with a framework called Rails.&nbsp;<\/p>\n\n\n\n<p><strong>Rails extends the Ruby language<\/strong> in the same way that .NET, Spring, or Django extend C#, Java, or Python, respectively.<\/p>\n\n\n\n<p>This combination resulted in the framework known now as <strong>Ruby on Rails (RoR)<\/strong>.
