Hello and welcome! Today, we're diving into practical data manipulation techniques in Go. We'll be using Go's slices and maps to represent our data and perform projection, filtering, and aggregation. The operations will be encapsulated within a Go struct, ensuring our code remains organized and efficient. So let's get ready to tackle data manipulation in a clean, idiomatic Go manner!

Data manipulation can be likened to sculpting — it's all about shaping and conditioning data to fit our specific needs. In Go, slices and maps offer powerful ways to handle and transform data. We'll harness these constructs within a Go struct to provide a tidy toolbox for our data operations. Here's a simple Go struct, DataStream, that will serve as the framework for our exploration:
