Coding is simple, no doubt about it! However, when a large number of developers in the community state that “React JS is just a javascript and any javascript developer may work on it,” a big issue arises. Therefore react js development is not as simple as it looks. 

In truth, React is essentially a javascript, but starting a React JS project without understanding all of its key capabilities will result in a skeleton with no muscles, liver, teeth, or anything else you can think of.

This post will teach you about some of the most typical mistakes that many developers make when working on a React JS project. Let’s go over some of these instances and see how we can implement each feature appropriately.

Mistakes While React Js Development 

Below are a few of the listed react js development mistakes that a developer can be made unknowingly to improve the website performance. But this can lead to the degradation of your website. 

1. Inadequate components

This is the primary mistake that every react js developer does during react js development. React provides us with a great deal of flexibility in how we structure and organize our apps. If you want, you can design an entire application in a single component. 

A single vast and intricate component can be difficult to grasp and comprehend. It can stymie debugging attempts and make extending your program more difficult.

Smaller, single-function components result in a cleaner, more readable code. These smaller functions can be combined (or composed). In this manner, you can construct complex interfaces from simpler building blocks.

This can help you cut down on copying and pasting in your codebase. You’ll construct your own component library over time, making it easier to stay consistent with your styling. It also makes reasoning about the ramifications of any code change easy.

2. Implementing logic in components

React is an incredible front-end framework. We can do amazing things with it! With Node.js or Deno backends, we can develop in JavaScript on both the front and back end.

The desire to not separate your arguments is something you must have noticed in teams like this. It can be difficult to pick where to put your logic when you can write it anywhere. This is less of an issue if we focus on building smaller, reusable components. We stop adding business logic to our components and instead concentrate on the reusable UI. Use helper or utility functions, or have your backend handle all of the heavy liftings.

3. Whenever possible, use stateless components.

This will help you with most of react js development React JS allows you to create two sorts of components: stateful components and stateless components. Which one you use is entirely dependent on your needs and preferences. 

The term “stateful component” refers to a component that handles states. So what if our component doesn’t have any state? Most of the time, we still create stateful components, which is not a good practice.

Because stateless components are free of lifecycle hooks, they save a lot of performance when used because React JS development does not need to perform any lifecycle operations, resulting in less processing. It also improves code readability by implementing a cleaner and more optimized coding standard.

4. Failure to adhere to React JS folder structure and other conventions

Any project established is not only for current development and standards, but it may also require maintenance or additional features in the future. When considering the future possibilities of react js development, standard convention and folder structure are critical.

A separate location for components, containers, and assets helps any developer traverse any existing project. Based on my improvements to these standards, you can also create new folders for hoc, shared, and other reasons. Its conception.

Following other conventions, such as naming, improves the readability of any codebase and can also help you to have an easy react js development. 

5. Use of redux that is unnecessary

Yes, how can we resist talking about redux? But, before you type npm install ReactJS-redux, should you think about whether you really need it?

In today’s world of simplicity and performance, every action is crucial. If your application includes a number of components that do not have a parent-child relationship but must communicate with one another, redux will come in handy. You do not need to include any additional libraries in your project if your application does not contain any parallel-level components that need to exchange information with one another.

6. While looping, no key is assigned

Looping over arrays is very clear when working on any React JS development project. React is no exception; it examines arrays in the same manner, but it also ensures that all iterations are detected and assigned a unique identity. For this, React employs keys.

Ensure that the key is always a unique value. Many developers make the mistake of assigning an iteration’s index as the key, which is a bad practice. If an element is deleted or updated, the index of that element can change at any time. Use a unique value, such as a unique id, as the key to help ReactJS identify elements more precisely.

7. You’re mutating states incorrectly

Working with states and props is central to React, but are you using them correctly? Most of the time, you enter mutating states unknowingly, leaving you clueless later.

This will prevent any undesirable state mutation and make your application work more acceptably without you banging your head against the wall wondering what’s wrong with your code.

8. Leaving aside the fact that setState is asynchronous

Because setState is asynchronous, you don’t know whether the state has changed until checking for it. This leads to application inconsistencies and, in many situations, catastrophic issues.

When we hear the word asynchronous, we immediately think of a callback. While your current operation is being completed, the setState method returns a callback that can be used to work on another operation. You may not need this very often, but if you do, the setState method’s asynchronous behavior is always available.

9. EsLint has the potential to save your life

There are several types of programmers; one can go the hard route or the clever way; it does make a difference. Hire React js developer who can take advantage of all of the advantages that React has to offer. EsLint helps you detect faults and problems faster by making your coding more consistent. This not only increases development speed but also helps to organize things.

We can encounter numerous problems, bugs, and a lack of understanding about various aspects while learning any technology and getting our hands dirty with actual development. This article attempted to cover some of these aspects that can save you a lot of time and allow you to focus more on logic.

Conclusion 

In conclusion to this, it can be stated that you can easily avoid these mistakes and have a good website or application. Moreover, in case you want to make web apps more efficiently you can go with a reputed software development company that has expert react js consultants. Thus, it is critical to learn about general and specific React JS mistakes to avoid while working on production-quality applications. Thus, if the state is used properly, the components’ productivity is maximized, and some widely-accepted rules, including those concerning functional components and hooks usage, are followed, the code can be dramatically improved.

Also, keeping the code tidy in terms of components’ structure, excluding prop drilling, and making the best out of React’s rich libraries can impact the speed of the development process positively. On the part of the application, continuous learning and updating with the new features of React and the new changes are also important for the long run. Listing and discussing these typical problems would help developers make the best of React JS, and reduce the possible negative impacts to the applications.
