Share Description
In this course, you will learn :
- provides the fundamentals that both new and experienced developers require to begin coding in Ruby, beginning with the core object types: numbers, strings, symbols, booleans, and more.
- Ruby's control structures, such as conditionals, loops, and iterators, are demonstrated.
- explains best practises for scripting and demonstrates the power of enumerables and code blocks
- You should be able to use Ruby to define your own custom methods with loops and conditional logic by the end of the course.
