Julia 1.0 Essentials

Learn the basic features of Julia for technical computing and data science

Douglas Eadline

This live training course covers the essential introductory aspects of the Julia Language. As of August 2018, version 1.0 of Julia has been released and provides an easy, high performance, robust, and stable platform for technical computing, data analytics, finance, machine learning, and mathematics. Installation on Windows, Macintosh, and Linux will be provided along with annotated example notes.

What you'll learn-and how you can apply it

  • Understand the need for the Julia language
  • Learn the standout features of Julia—and how you benefit from them
  • Install Julia on Windows, Macintosh, or Linux machines
  • Learn the basics of Julia 1.0 with hands-on demonstrations of the Julia interpreter, iJulia (Jupyter notebook for Julia), and explore essential language features
  • Create standalone programs and use the new Julia 1.0 package manager

This training course is for you because...

  • You're a developer who needs both ease-of-use and fast execution speed in the same language
  • You are a technical computing user who prefers not to learn C or Fortran
  • You're a Python, R, or Matlab programmer who needs better performance
  • You're a domain specialist, data scientist, engineer, mathematician, or scientist who wants an easy-to-use, high-level, portable, and fast programing framework


  • A basic understanding of computer programming (Types, Variables, and Operations, Flow Control)
  • Some background in Linux shell commands is helpful, but not required

Course Set-up:

Recommended Preparation:

  • These are optional resources that you may find helpful as you brush up on fundamental computer programming and Linux shell commands (instruction will take place on a Linux machine) Bash Scripting (video)
