This chapter helps solidify your grasp of Julia's core programming principles and points towards avenues for further skill development. We will start by reviewing the key concepts presented throughout this course. Then, practical examples will illustrate multiple dispatch in action, reinforcing its utility. You will also get a first look at DataFrames.jl for working with tabular data and Plots.jl for creating basic visualizations, two significant packages in the Julia ecosystem. Finally, the chapter provides suggestions for continued study, introduces helpful community resources, and outlines a small project to put your new skills into practice.
