6a. Overview and Goals

Martin Alfaro
PhD in Economics

The previous chapter equipped us with techniques for manipulating vectors. We now expand our toolkit by introducing other data structures and common functions for data analysis.

Specifically, Section 6b introduces additional types for collections, including dictionaries and named tuples. Building on our grasp of tuples and vectors, we're now well-positioned to understand the unique features of these alternatives and understand when they're more suitable.

Meanwhile, Section 6c expands on tools for streamlining code, which are worthwhile for a daily use of Julia. These tools will make your coding experience smoother, by reducing boilerplate code and improving syntax readability. One notable example is the use of pipes.

Additionally, Section 6d introduces standard functions for data manipulation, such as removing duplicates, sorting elements, and rounding numbers.

To conclude the chapter, Section 6e puts into practice the tools we've covered. This will be done by analyzing data from a hypothetical scenario involving a YouTuber's earnings. While data analysis is generally carried out by using specialized packages such as DataFrames, the example will prepare you for a seamless transition to those powerful libraries.
