Learn React: Importance, Skills, and Training Paths
Mobile and web applications make day-to-day activities such as banking, ordering groceries, and listening to music easier and more convenient. With these benefits comes an increasing consumer and business demand for new apps, creating opportunities for developers looking to enhance their programming language toolkit.
Programmers often use frameworks and libraries like React.js to improve the efficiency of mobile and web development while helping ensure seamless experiences. Other popular languages, such as Angular, help improve web and mobile app development. So why learn React?
Ranking second only to ASP.NET as a favorite web framework according to a 2020 Stack Overflow survey, React provides rich features for fast, flexible, and simple web and mobile app development. React allows programmers to develop flexible user interface designs that are easy to use and responsive.
Salary is also often a key consideration for individuals interested in learning a new tech skill, and compensation for those with React.js expertise is quite competitive. According to Payscale, the median annual salary for experienced individuals with React skills was approximately $94,000 as of May 2022.
Why Learn React
Developers learn React for different reasons. For some, it’s the ability to develop cross-platform applications that look and feel native. From a business perspective, organizations and agencies may ask their programmers to learn React because it’s fast, scalable, and easy to use, allowing businesses to build intuitive mobile apps. Among the primary advantages of React are its reusable components, which optimize the app development process through time savings, improved productivity, and reduced cost.
Here are a few other reasons why programmers should consider learning React:
Easy to Learn and Use
React houses many ready-to-use components so that programmers can develop fully functional web and mobile apps without learning a new framework. It includes an extensive set of library functions that developers can assemble to build custom functions and features and flexible user interface (UI) designs. When it comes time to customize, programmers can build upon existing templates and features.
A programmer who develops a web app may also need to develop similar functionality for mobile devices. Frameworks like React provide developers with tools, code libraries, and a foundational structure to port a web app to mobile without starting from scratch ― no need to reinvent the wheel every time, which saves time.
With React, developers can be engaged throughout the entire UI component design process, from project launch to final testing. Therefore, understanding the software development process is helpful. Soft skills such as communication and collaboration are also critical competencies for React JS developers, as they often work in team settings. And because issues can arise, problem-solving and analytical thinking skills are necessary for coming up with effective solutions.
React developers can also benefit from having a command of different languages, knowledge of key development tools, and an understanding of basic and advanced React features and functions.
Basic React Topics
HTML + CSS
HTML (Hypertext Markup Language) is the language used to structure webpages. It works with CSS (Cascading Style Sheets), a language that defines how a webpage will look, including colors, layouts, and fonts. These two languages are separate, but together, they form the basis of webpages and web applications.
Throughout the development process, software code changes as different programmers work on it. To help keep track of these changes, programmers use Git, an open-source system for version control developed in 2005. Version control means tracking and managing software code changes. Through Git, programmers can identify changes in code and more easily collaborate with others to collect, approve, alter, or merge the code into a single source.
Props and Functions
How do components communicate? A special object in React called a prop (short for property) transports data from a parent component to a child component. In other words, a prop is a one-way flow type of communication. A type of prop called a function allows a child component to transport data to the parent component.
React Advanced Topics
A breakdown of the software code in web or mobile apps reveals a logical structure of documents that must be accessed and manipulated so that users can see the intended content in the UI. A Document Object Model (DOM), an application programming interface (API), is the software element that establishes the logical structure of documents and how they’re accessed and manipulated.
A key challenge with using a regular DOM is rerendering the logical structure when changes are made to the code. A developer must manually manipulate the attributes of DOM elements and then update the DOM. React’s virtual DOM represents the actual DOM in the UI’s memory, and syncing is more automated, helping to address inefficient rerendering processes.
Web workers were developed to help solve this problem, running in the background to allow the running of multiple scripts without hindering the primary script from completing its tasks. This results in a responsive, high-performing UI.
Steps to Learn React
Not every React programmer will take the same educational path, but there are two common steps every individual typically takes to learn React and develop their skills.
First, understanding the purpose of React is important. This information, including the history of the language and case study examples, is available throughout the web.
With a foundational knowledge of React, its purpose, and its benefits, the next step is to learn the language. No single approach works for all aspiring React programmers. Some may wind up in a formal setting, such as a college classroom. Others may enroll in a shorter skills training program, or engage in self-education at their own pace.
The following options can help aspiring programmers learn React, depending on their career goals and time frame.
Tutorials and Videos
Self-teaching via various React tutorials, exercises, and videos available on the web can work for individuals who thrive in self-paced education without guidance, but grasping concepts without hands-on support can be time-consuming and difficult. For individuals without the time and focus to commit to learning React on their own, this learning path may be less effective.
Formal education from universities, private schools, and paid courses can offer the structure and schedule to help programmers learn React and begin writing code. These options can be expensive and lengthy, however, and working professionals may struggle to achieve a healthy work-life balance while learning React in a full-time classroom setting.
Technology Training Organization
Technology talent organizations offer another path. They provide training and connect candidates with employers with open programmer positions. Revature’s hire-train-deploy model can help people looking to break into a tech career get trained on in-demand skills such as React. Revature pays associates during training and offers employment opportunities at the end of the process.
React Exercises and Quizzes
A key way to develop and strengthen one’s skills is through React exercises and quizzes. Individuals can advance their knowledge or familiarize themselves with React concepts, syntax, and language with these tutorial exercises and quizzes.
In addition to knowing React basic concepts, learning how components work is important. For example, React enables developers to create dynamic websites with reusable components to create effective UIs while greatly reducing development time. Understanding components also means enabling them to communicate with each other, which requires knowledge of the role of props and functions.
JSX, components, and the role of behind-the-scenes elements such as virtual DOM are other areas developers should learn. Another key topic is the role of Git for tracking changes and managing source code in webpages and web apps.
