Programming Languages and - Why Julia?

Installation

Make sure to check out the installation page on this website before you come to class.

Basics: REPL, VSCode, Notebooks

We will repeat the basics of julia in a very condensed manner by going through steps 1-7 of MoJuWo live in class.

julia REPL:

This is the julia REPL

VScode:

This is VSCode

Notice how there is a julia REPL running as part of the VSCode editor. This is called an integrated development environment (IDE). Very similar to an R session connected to RStudio, or the python interpreter being run through PyCharm etc.

Introduction and: Why Julia?

In this section we want to understand why julia is a good choice for computational tasks - for Economists and others.

We use several Pluto.jl notebooks in this lecture. Here are four rendered ones:
