React JS is an efficient JavaScript library for building user interfaces. Facebook and Instagram develop it, and it is open source. It became popular in recent years thanks to its flexibility in application development and the ability to create interactive UIs. It's a library of reusable components that can be combined to create complex sets of UI elements. React JS is about building the UI as a function of the underlying data. It's not just about creating a static representation of the data - it's also about how changing the underlying data changes the UI. React JS has been around since 2013, becoming one of the most popular frameworks for building user interfaces on the web today. React JS has many benefits. It is easy to learn and offers a wide range of documentation. It has a low learning curve, and It provides an intuitive API. React JS is fast because it uses one thread per render (which makes it easier to scale). It's great for web applications that require real-time data updates.
A React hooks callback is a function that is passed to another function as an argument. The callback is executed when the first function finishes its job. The callback can be called in three different ways: Asynchronously, where the first function starts running and then calls the callback at some point later on. Synchronously, where the first function executes and then immediately returns control to continue execution of the calling code. When a Promise is produced from the first function, it will call all callbacks registered with it once it fulfils or rejects. Custom Hooks with callbacks are a perfect way to use callbacks for DOM manipulation. They can be used when you want to make changes to the DOM after an event has occurred. The benefits of custom hooks with callbacks are that they allow you to execute code at a specific time or place in your code, and this is much simpler than using the `setTimeout` function.
