Article Introduction：reactive is a function in Vue.js used to create reactive data. Its function is to convert ordinary JavaScript objects into reactive objects so that they can automatically update the view. With a dependency tracking system, when the value of reactive data changes, all view components that depend on that data are automatically updated, simplifying development and optimizing performance.

Article Introduction：1. What are ref and reactive? They are the APIs used to implement data responsiveness in Vue3. Generally, ref defines the basic data type, and reactive defines the reference data type. 2. Let’s talk about reactive first. Reactive defines the reference data type (taking objects and arrays as examples). It can declare internal properties or data items of complex data types as responsive data, so the responsiveness of reactive is deep-level. The bottom layer is to implement data responsiveness through ES6's Proxy. Compared with Vue2's Object.defineProperty, it has It can monitor additions and deletions, and changes in object properties. Use reactive to define the number of objects.

Article Introduction：The obj parameter in the reactive() function in Vue represents the original object to be converted into a reactive proxy object. This function makes an object reactive by hijacking its properties and notifying Vue of changes, ensuring that the proxy object behaves the same as the original object, and creating a proxy object that can be observed by Vue. Usage scenarios include making data objects reactive, nesting within other reactive objects, and converting third-party library objects to reactive.

Article Introduction：SpringBoot is a framework for quickly building applications, while reactive programming is a method for efficient and high-load data processing, which can make applications more responsive and robust. In this article, we will discuss reactive programming and reactive system design with SpringBoot. Reactive Programming In the traditional programming model, a request is sent to the application, and the application blocks until the request is completed, which causes the application to become slow and clunky. Therefore, we need

Article Introduction：Java development: How to use Vert.x for reactive programming Preface: In modern application development, reactive programming has become an important concept. It provides an efficient and scalable way to handle asynchronous event streams and data streams. Vert.x is an excellent reactive programming framework. It is based on an event-driven architecture and can well handle high concurrency and large-scale data processing requirements. This article will introduce how to use Vert.x for reactive programming, with some specific code examples. Introducing Vert.

Article Introduction：Reactive programming is a programming paradigm that handles asynchronous data flows. It's a way of writing code that responds to changes more quickly and handles events and data flow more efficiently. In reactive programming, data is represented as a stream of events. These events can be anything from user input to network requests to database updates. The program then subscribes to these events and reacts when they occur. This programming method has many advantages. First, it makes working with asynchronous data easier. In traditional programming, asynchronous data can be difficult to handle because it is difficult to know when the data will be available. Reactive programming, on the other hand, handles asynchronous data in a more natural way by treating it as a stream of events. Secondly, reactive programming helps improve the performance of your code. pass

Article Introduction：In Vue, reactive creates responsive objects, and attribute changes automatically update the view; ref creates mutable reference objects, and modifying the .value attribute does not trigger updates. Specific differences: the reactive object remains unchanged, and you need to use Vue.set() to modify the properties; the ref object is mutable, and the .value property can be modified directly. reactive is used for data that needs to be automatically updated (such as model data); ref is used to control updated data (such as form input or refs).
