Best React Developers Skills That You Must Look into in 2023

  1. HTML and CSS
  2. JSX
  3. JavaScript Fundamentals and ES6
  4. Git
  5. Node and NPM
  6. Redux

Today, React is the go-to library for front-end developers. Simply put, learning React improves your development skills, and many organizations value these abilities. React developers should be eager to improve or audit the skills required by Facebook’s well-known JavaScript Library.


A front-end developer is not unfamiliar with HTML and CSS. Every organization needs to be able to create user interfaces and work with them. Developers using React should be able to:


You’ll use the JSX syntax extension in React, which is unquestionably one of the most amazing components of the React ecosystem. The cool thing about JSX is that you can work with it naturally if you are familiar with HTML and CSS.

On top of the React.createElement() API, JSX is an abstraction. The API would be too difficult to use in terms of scaling, which is one reason it is essential to the library and why the React team initially went with it. Although one could theoretically construct an entire application using React.createElement(), doing this is no more efficient than just using HTML.

Java Script Fundamentals and ES6 

Without a full understanding of the principal factors provided by the JavaScript language, you can’t rock React, but these ES6 skills are also crucial:

Variables and Scope:

It’s crucial to know when and where you can access the data you require. The mechanism provided by JavaScript’s variables enables us to store data in memory and access it later in our applications.

ES6 introduced new keywords (like “let” and “const”) that we can use to store variables in addition to the conventional “var” keyword. You can choose to follow the rule of thumb “Use ‘const’ until your linter tells you otherwise, then default to ‘let’ unless you do not even absolutely need to use ‘var’

Objects and Arrays:

Your “view is a function of your state,” as React suggests, is a pattern. To put it mathematically, that is “v = f(s),” and you should keep that in mind as you review your understanding of the library’s fundamentals.

State refers to data in memory that is accessible or data that we want to display to users so they can interact with our data. All of the data that we present is stored on a state object, and we can access it using its properties. React got its name because the view updates when the state does (‘v = f(s);’). As a result, when your state object is modified, your view “reacts.”

You should review how to modify objects and alter the values of their properties. To make this work in your favor, React takes care of the process with the help of a handy function called “setState().”

Array Methods: 

It’s one thing to be able to access and store data within objects and arrays. It’s another to have the ability to handle that data properly. Every developer’s toolkit should include the built-in JavaScript array functions. For optimum impact, rely on “.map,” “.filter,” and “.reduce.”

Functions and Arrow functions:

Every component you create in React is, in some way, a function. Keep in mind that, at their core, “classes” are really “function Object() { [native code] } functions.” When creating “functional components” or “class components,” you use a function in some capacity, regardless of the syntax you choose.

There are many current practices that support functional programming. It’s similar to assembling a Lego set without instructions to have the opportunity to use JavaScript methods to build out little portions of the UI. Each UI component is an enclosed function that includes the parts themselves, the formal component logic you need to apply that logic, and the state information your elements must present. Each component is a Lego brick, and it’s up to you to fit them all together.

DOM Manipulation and event handlers:

It is uncommon in React to manipulate the real DOM elements. Keep in mind that we are now able to use the JSX abstraction. The SyntheticEvent is actually a wrapper for the native event object that you obtain with standard DOM manipulation in React. Make sure you can attach various events, such as “onclicks,” “onchange,” “mouseenter,” etc., to HTML elements.

The ‘this’ keyword:

One of the JavaScript features that is frequently overused is the “this” keyword. Consider “this” as a pointer to an item. For instance, you don’t need to mention the object’s name to access an object when using the ‘this’ keyword.

Higher order functions and callback functions:

The “input/output” concept of functional programming is what drives high order functions and callbacks.

In React, handlers are passed all over the place. The handlers you pass around are frequently methods chained onto objects that can be accessed as properties and are wrapped up in the prototype chain. However, there are times when you need to go beyond the React component paradigm or build a few other kinds of components that complement one another in terms of functionality. These patterns, which are also known as advanced React patterns, are starting to make their way into the category of better/common practices. As you scale using React, you’ll be pushed to be imaginative and creative.

Prototypal inheritance and object creation:

In many ways, React is well-suited to the functional programming paradigm. But you operate in a world of classes, which leads to a world of object creation. You will be able to understand inheritance in JavaScript if you have a fundamental understanding of how the prototype chain functions. Keep in mind that JavaScript lacks standard classes. 

The ‘Class’ Keyword:

JavaScript classes differ from traditional programming classes in several important ways. You build classes that contain formal JavaScript code, your template logic, and even styles known as components. Any React application is built from these components, and there are only two methods to write a basic component: either by declaring it as a function or as a class.


Every developer needs Git to store projects on platforms like GitHub, Bitbucket, and GitLab. The following are abilities that should be part of your routine:

Node and NPM

Many people could be shocked by Node. Why would working with Node be necessary for a client-side React developer? Although you may include React in any HTML document, there are many more packages available that will let you add more functionality to the React framework.

Developers working with React must be well-versed with the npm registry. This is the location where software developers can get the tools they need to create software. Sounds absurd, but that’s all npm is: a cloud storage system for the packages we refer to as dependencies.


A package manager called Yarn was created with the npm registry in mind. Your npm workflows are actually optimized by yarn. Today, Yarn and npm compete to some extent, although Yarn’s goal has been to address many issues that are common in the Node/npm ecosystem. npm has been making every effort to adhere to the guidelines and procedures that Yarn offers.


Hot button issue warning: State management has been built into React. Along the road, many developers have suffered setbacks after learning about the asynchronicity of state updates and how React manages them. Redux was created due to this and for scalability. Redux is more than just a state management library. It is an opinionated method of dealing with data rather than a framework. Although functional programming and immutability are the guiding concepts of Redux, it is not a one-size-fits-all approach. It’s important to understand the fundamentals of React programming before launching into Redux.
