Le Wagon prefer not to follow the hype and base the program on a more long-lasting foundation. We truly believe you should NOT attend a bootcamp to learn a language, but to be able to deeply think as a software engineer: someone who is capable of breaking down problems into software components and build solutions from the ground up.
1 - It's the first language that puts the developer at the center of the creation process. Most languages were created with the machine in mind (robustness, stability, performance...). The consequence is that computer languages can be unintuitive and complex to learn. Ruby is concise, elegant and reads like English, so students can focus on developing their logical thinking rather than memorizing the syntax.
2 - Ruby is object-oriented programming: it means that the building blocks of programming are transversal to all of them (variables, functions, strings, arrays, hashes). Once you learn object-oriented programming, you'll be ready to acquire new skills in other back-end languages. Most of Le Wagon graduates who are now working as professional developers are coding in several different languages, frameworks and stacks, from Elixir to Python.
3 - Paired with Rails (an open source framework created by a startup founder and author of the book "Rework" David Heinemeier Hansson), it brings an extremely efficient way of building web apps. Ruby on Rails has an amazing community of developers and was used to build companies like Airbnb, Github, Twitter, Soundcloud, Kickstarter and Shopify.
