Overview/Description
Software development requires the use of data types and flow control in order to build most applications. In this course, you can explore Ruby data types and how to manipulate them. You will learn how to work with loops, and also While, Unless, and Until statements to repeat Ruby tasks. Next, program decisions with ternary operators and case statements. Walk through data sets with sequence ranges. Hash it out with the Ruby associative array data type to store and use a built-in key-value store. Learn Ruby encoding, numerical, and bang methods. Manipulate strings. Finally, observe the question mark convention in Ruby.
