Julia is a flexible and dynamic programming language which is usually used for scientific computing. In a short span of time, the popularity of this language has grown exponentially due to its speed, dynamism and for ease to use. The demand for learning Julia has gone up manifolds and with this article, we list down 10 online free resources where you can learn Julia language from scratch. These resources will especially be quite useful for beginners who have never ventured onto this language before.

(The list is in no particular order)

1| Official Documentation On Julia

This is the official documentation on Julia language where you can learn the scientific computing language from scratch. You will learn about the strings, functions, types, variables, libraries, etc.   right from the basic introduction to developing and debugging Julia’s code.

7| A Deep Introduction to Julia for Data Science and Scientific Computing

This tutorial starts by introducing the basic syntax of Julia language and quickly moves into the details of how this language is different from other scripting languages and how to exploit Julia’s type system including multiple dispatches to be able to achieve C/Fortran-like performance while maintaining the concise syntax of a scripting language. You will also learn how to design Julia projects. The major goal of this tutorial is to use Julia’s language and syntax to bridge the gap between “package users” and “package developers” in the way that Julia has done.

8| Julia Scientific Programming (Online Course)

The course is divided into four modules and introduces Julia as a first language. The extensive assignments teach you the language with much ease and enable you to write your own Julia program from scratch. It also equips with understanding the advantages and capacities of Julia as a computing language, work in Jupyter notebooks and use  use various Julia packages such as Plots, DataFrames and Stat.
