Client-server connections are typically made via HTTP using a request-and-response model. In other words, when new data is required, the client sends a request to the server. The server then checks the request and sends a response to the client. At this point – and not before – the data becomes visible. WebSocket establishes a two-way connection that makes this process much quicker, even without a...

Low-code is therefore particularly suited to technical amateurs who are unable to write complex code. But professional developers also use this method to save time and costs when developing software applications.
