React is an open-source JavaScript library that was created by Facebook to help developers build user interfaces for web applications. It is currently one of the most popular front-end technologies in use today, and it is used by many large organizations like Netflix and Airbnb. 

Understanding React

Based on the idea of reusable components, which are small, self-contained pieces of code that can be easily combined to create complex user interfaces (UI), React allows developers to write modular code that can then be reused across different parts of their application. React uses a declarative programming style, meaning that developers write code that describes what they want their application to do, rather than how to do it. 

Benefits of React

One of the key benefits of React is its virtual DOM, or Document Object Model, which is a lightweight representation of the actual DOM. When a user interacts with a React component, the virtual DOM is updated instead of the actual DOM, which is faster and more efficient. Once the virtual DOM has been updated, React compares it to the previous version to determine which parts need to be updated. This process is known as reconciliation, and it allows React to update the UI in an efficient and optimal way.

Another benefit is that React is highly extensible, and therefore can be customized and integrated with other technologies. For example, React can be used with Redux, a state management library, to manage the state of an application in a predictable and centralized way.

Finally, React can be used together with back-end, like Python framework or Django, to build full-stack web development applications. The ability to combine these frameworks allows developers to create complex, modern, and interactive web applications.

Learn React with Momentum

At a coding bootcamp like Momentum, students are introduced to React as part of their advanced front-end web development, learning how to use the technology to build reusable components, manage state, and interact with APIs. Since React is one of many front-end frameworks, and arguable more important nowadays, it can be used with static site generators as part of the modern “Jamstack.”

Throughout the training process, students gain practical experience working with a popular and in-demand technology, learn best practices for writing modular and reusable code, and complete rigorous projects using React.

In teaching our students React technology, we not only improve their job prospects and make them more competitive in the job market with a robust portfolio, but we also help them become more efficient developers and improve the quality of their code.

Final Thoughts on React Technology

React is a powerful and popular technology that is widely used in the tech industry for front-end web development. Based on the idea of reusable components, it uses a declarative programming style that is easy for developers to use. Learning React at Momentum can equip students with practical experience to succeed in their post-Momentum careers in software development.
