Factory pattern helps to generate object by choosing one class from a bunch of classes. The class is chosen by some predefined criteria. This article demonstrates Abstract Factory pattern implementations in Java.
Singleton pattern is used to ensure that, only one instance of a class can be created. This article demonstrates Singleton pattern implementations in Java.

Server-Sent Events(SSE) complete tutorial.

The data you are trying to parse in JavaScript is already a JavaScript Object. When the JSON.parse(data) tries to parse a string to JSON, it expects a string. And it is getting a JSON object already, which has the “o” (from the “object”), so JavaScript can not parse it.
This article will explain, how to implement Server-Sent Events(SSE). Let’s discuss it step-by-step. Let’s create the simplest SSE server in PHP.
Server-Sent Events(SSE) are used to implement real-time communication, where the server sends data to the client. In this article, we have discussed all the details of the SSE implementation. All the headers and options are covered in this article.
Using the Factory pattern we generate objects based on some criteria. In Abstract factory pattern, we use multiple factory pattern implementations and generate objects based on that. Abstract factory pattern is also called Factory of Factory, so before reading about Abstract factory pattern, take a look at the Factory pattern.
