Ruby Essential Training Part 1: The Basics

Course details

Ruby, the popular object-oriented open-source programming language, is a great place to start learning programming or web development. You can use it to write interactive programs or build scripts to speed up common tasks. In this course, instructor Kevin Skoglund provides the basics that new and experienced developers need to know to start coding with Ruby, starting with the core object types: numbers, strings, symbols, booleans, and more. He demonstrates Ruby's control structures, including conditionals, loops, and iterators. Kevin explains scripting best practices and shows the power of using enumerables and code blocks. By the end of the course, you should be able to use Ruby to define your own custom methods with loops and conditional logic.
