The advantage of a wikibook is that anyone can edit anything at any time. In theory, a wikibook will only get better, as more people add improvements and corrections. In practice, a wikibook can lose focus and consistency even while it gains accuracy and coverage. But because the Julia community has established a good ethos of encouraging participation in the development of the language, it's right that this wikibook is freely editable by everyone. So feel free to correct and improve anything you read here, although keeping the focus on the new user rather than the computer science guru is recommended. |

Introduction
Julia is a recent arrival to the world of programming languages, and tutorials and introductory texts are now starting to appear.
The official Julia documentation is excellent, but it's aimed primarily at the early adopters, developers, and more experienced programmers. You should refer to it as often as possible.
In addition to the many introductory videos and online Julia blog posts and notebooks, you can purchase (or order) the following Julia tutorials:

This wikibook (which predates all these publications) is however, less of a tutorial, and more a collection of notes and examples to help you while you're learning the lanaguage.
The advantage of a 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 Julia community has established a good ethos of encouraging participation in the development of the language on github. In the same way, this wikibook is freely editable. The focus should be largely on the new user, rather than the computer science expert.
This wikibook has been mostly updated to work with the new version of Julia, version 0.4, which, as the time of writing (September 2015), is due to be released in a few weeks.
