Warm greetings! This lesson introduces data streams, which are essentially continuous datasets. Think of a weather station or gaming application gathering data per second — both generate data streams! We will master handling these data streams using TypeScript, learning to access elements, slice segments, and convert these streams into strings for easier handling.

In TypeScript, data streams can be represented using arrays, with additional TypeScript features like type annotations that improve code readability and robustness.

Consider a straightforward TypeScript class named DataStream. This class encapsulates operations related to data streams in our program:

To use it, we create a sample data stream as an instance of our DataStream class, where each element is an object of type DataElement with two properties, id and value:
