React 18 has some of the best functional dependencies designed with a vision to boost performance and make things easier for developers. the newest version has distinctive functionalities to overcome the stumbling blocks included in the previous version.
It is used to design creative APIs and render HTML files, in contrast with a vast collection of libraries of experts and authors to give considerable inputs to build you up as an outshining developer
New Features:
- Concurrent React
- Improvement in Automatic Batching
- New Start Transition API to Keep Your App Responsive
- New Suspense SSR, Architectural Improvements
- IE11 No Longer Supported
New APIs/Hooks startTransition(), useTransition(), useDeferredValue()
- Concurrent React — It is the most useful feature added to the react 18 features list, from solving a highly problematic concurrency issue. The concurrent react is a virtual element that eases the developers to have multiple instances of their UI, all at the same time. The reusable state is the handy feature that comes along the way with the Concurrent react. It can discard some UI sections and use them again after rolling to the previous model.
- Improvement in Automatic Batching — React 18 has an improvised form of Batching called React 18 Automatic Batching that batches all the state updates through createRoot. The background of the updates is not necessary, and the process involves functions such as timeout and intervals, asynchronous applications, event handlers, and batch state updates.
- New Start Transition API to Keep Your App Responsive — The developers can set a priority list based on the updates happening frequently. The essential updates occur with direct contacts such as a click, type, press, and other functions. These updates are carried out instantly as per the developer’s requests.
- New Suspense SSR, Architectural Improvements — React suspense is a feature that allows the developers to keep an eye on the rendering components till the process continues. It has a fallback feature which is then displayed. With the latest React version, this feature can be combined with the transition API. It prevents the content from being replaced and even delays the rendering schedule to reduce the loading effect.
- New APIs/Hooks startTransition(), useTransition(), useDeferredValue() — React has some predefined hooks to perform a specific task as per the developer’s request.startTransition()- It is an API used to determine the availability of a particular transition. This API refers to the state update that the developers want to operate. The updates wrapped up in the startTransition API are considered non-urgent updates. They can be overridden by urgent updates such as keypress, click, etc. A code snippet depicting the use case of the startTransition() API is shown below. useTransition()- It is used to create new state updates with priorities lower than the existing ones. It returns both the transition state and a function to initiate the start transition API. The use case of the useTransition() API is figured out below. useDeferredValue()- It is a hook that takes a value as a parameter and creates a duplicate copy of the same value. The new reference defers to an update that is more urgent than the previous one. Once the urgent updates are compiled, the new value is further rendered. We have an example shown bel
- IE11 No Longer Supported
React 18 does not support the IE11 feature and the developers switching to react 18 could no longer use it. So, if your project still works on the IE11 quality, you must not upgrade it to the latest version.
