This chapter introduced you to Julia, how to download it, install it, and build it from source. We saw that the language is elegant, concise, and powerful. The next three chapters will discuss the features of Julia in more depth.
We looked at interacting with Julia via the command line (REPL) in order to use a random walk method to evaluate the price of an Asian option. We also discussed the use of two interactive development environments (IDEs), Juno and IJulia, as an alternative to REPL.
In addition, we reviewed the in-built package manager and how to add, update, and remove modules, and then demonstrated the use of two graphics packages to display the typical trajectories of the Asian option calculation. In the next chapter, we will look at various other approaches to creating display graphics and quality visualizations.
