This blog will discuss the recently released features of React 18 and how they will help developers with their issues. 

React 18: What's New? Updates and New Functionality 

 React has been making waves in the development community with the best React libraries to the creation of cross-platform frameworks known as React Native. It's making waves once more with React 18, the most recent version.  

Is React 18 Worth the Hype?  

React 18's primary focus, according to the official React website, is on its new concurrent functionality, which is only activated when you use a modern part. On the other hand, it will have a significant impact on React app development.  

 Let's now examine the characteristics of React 18 below.  

React: 18 New Features You Can't Ignore  

1. Development Exclusively In strict mode  

Software projects are frequently developed by a group of developers. It's possible that a new React developer needs to adhere to recommended practices when crafting the code. That's where Strict Mode comes in handy.  

React tools like strict mode inspect your code and issue warnings when any of the rules are broken. It makes sure that the final product is more comprehensible and well-organized code because it highlights the errors in the code. Even while React has had Strict Mode for a while, React 18 updates have greatly expanded the functionality of these features. A few of them consist of:  

  • Now that two or more jobs are running concurrently, a strict mode can detect flaws.  
  • Production time is not hampered by the mode because it only operates during development.  

  • The new Strict mode provides more errors and warnings than the previous one. Additionally, it loads functions twice to guarantee that the desired outcomes always materialize.   

2. The server's suspense  

Understanding server-side rendering in React is vital for understanding the suspense of the server world. SSR is the server-side rendering (display) of React components. So, initially, the server generates HTML, which is then loaded into the browser. Users will still be able to see the apps on the screen in this manner. The main distinction is that they can only interact with the app or site if it is completely rendered.  

To comprehend this update, let's first define suspense. is a React element that is used to impede the rendering of React components. Before the release of React 18, could not be used on the server. As a result, is now available on the server, which will help with server-side rendering.   

3. Automated Batching  

To group updates, the React language uses the batching feature. The advantage of batching is that each component is not rendered individually, which improves performance.  

However, only webhooks and browsers were batchable with React 17. The main problem was that when the application grew in size, so did the code because developers had to add batching code separately.  

As a result, automatic batching became available in React 18. As a result, regardless of whether components require a state update, React will batch the updates without adding them to the code.  

Automatic batching in React 18 is essentially the same as picking up a bunch of blocks at once and stacking them together instead of doing it one by one. It allows your program to run faster and more efficiently!  

4. Concurrent Rendering Engine  

Let's look at an example to better grasp concurrent rendering. Assume you have two meetings on the same day. In a non-concurrent circumstance, you would take the meeting with one person first, then hang up and start another meeting.  

 If the call is brief, this circumstance is OK. But what if the first encounter goes on longer than planned? The second individual would have to wait for additional time, wasting time.  

Previously, rendering was a single, synchronous, and non-interrupted event in React. This signifies that the second event will not be rendered unless the first event is completely rendered.  

 To avoid the time sinks stated above, React 18 added a parallel rendering engine that can stop, pause, or terminate the first event to render the second. The benefit is that users need not wait, which improves the overall user experience.  

5. Transition 

To distinguish between urgent and non-urgent jobs, React included a transition function. The primary goal is to assist developers in prioritizing updates that they anticipate that clients will interact with more frequently.  

The transition concept serves two primary purposes:  

  •  Transfer the user interface from one view to the next.  

  • Urgent updates are based on direct inputs such as clicking, pressing, typing, and so on.
