Welcome to the world of data streams! In Go, we utilize slices and maps to handle these continuous datasets efficiently. Whether you're observing a weather station or analyzing game sessions by the second, Go enables seamless data stream management. This lesson will guide you through accessing elements, slicing segments, and converting these streams into strings for better readability.

In Go, we represent data streams using slices and maps. Below is a simple implementation of a DataStream struct, which encapsulates operations on data streams:

Here, we define a slice of maps, each element of which represents a part of our data stream. The sample data point type {"id": 1, "value": 100} contains an id to uniquely identify each element and a value representing the stored data, enabling structured and easily accessible data representation.

To access individual elements of a data stream, we use indexing. Below is a Get method that retrieves the -th element from the data stream:
