Deepen your knowledge with human mentoring.
Discover new and exciting ways to approach an exercise by getting mentored on it. Become more familiar with the conventions, idioms and opinions of a particular programming language.
Why mentoring?
You don't know what you don't know
When learning a new language, the hardest part is not being aware of the gaps in your knowledge. Our mentors can look at your code and immediately see the ideas you're not familiar with
Learn language-specific conventions
Becoming fluent in a language is more than being able to write code in it - it's about being able to think in that language. Our mentors will help guide you to how to reshape your thinking to write idiomatic code.
Learning with others is fun
Getting feedback from real people is an amazingly exciting way to learn. And becoming a mentor and giving feedback yourself is an even bigger step forward. So complete the circle - be mentored and mentor 🎉
