What exactly are asynchronous data streams? Let’s take each word separately and put it into context. Asynchronous, in JavaScript means we can call a function and register a callback to be notified when results are available, so we can continue with execution and avoid the Web Page from being unresponsive. This is used for ajax calls, DOM-events, Promises, WebWorkers and WebSockets. Data, raw information in the form of JavaScript data types as: Number, String, Objects (Arrays, Sets, Maps). Streams, sequences of data made available over time. As an example, opposed to Arrays you don’t need all the information to be present in order to start using them. Asynchronous data streams are not new. They have been around since Unix systems, and come in different flavours and names: streams (Node.js), pipes (Unix) or async pipes (Angular 2).
