Ruby is a programming language developed in the 90s by Yukihiro ‘Matz’ Matsumoto. I’ve found that studying Ruby is a bit like learning a foreign language minus the speaking bit. In order to solve problems using the language, you have to learn how to think in the language. So far, this is still a work-in-progress for me. In comparison to some of the other programming languages I’ve encountered, its syntax is more simplified and forgiving. I believe this is why this is a popular backend programming language among beginners.

This week I learned about arrays and hashes. Even though arrays and hashes are used to create collections of items, they differ in usage.

In the examples below, I created examples of an array and hash on repl.it, an online coding site. In the first example, I created an array called ‘favorite_movies.’ Each movie responds to an number 0-5. In Ruby, numbers are referred to as integers. The second example is a hash called “tv_shows” created using keys and values.
