Introduction[edit | edit source]
The Julia programming language is easy to use, fast, and powerful. This wikibook is intended as an introduction to the language for the less experienced and occasional programmer. For more learning materials, including links to books, videos, articles/blogs and notebooks, refer to the learning section at Julia's official site.
The official Julia documentation is excellent, and you should refer to it as often as possible.
The Julia community has established a good ethos of encouraging participation in the development of the language on github. The advantage of this wikibook is that it's made and edited by the Julia community – you can edit anything at any time. If you find something that's wrong, or unclear, feel free to correct it, or add examples. (Your first few edits are reviewed, just in case you have less than good intentions. And, as with the Wikipedia, you should expect your writing to be edited by others!) The focus should be largely on the new user, rather than the computer science expert.
