Considering the popularity of mobile apps, the need for React developers has risen significantly. The framework offers developers a way to create fast, scalable and easy to maintain systems. It has also become a preferred choice among developers for creating visual interfaces. Several companies use React, including Netflix, Instagram, Airbnb, and Uber Eats.
React developers work across the entire app production process, from wireframes to final UIs. They must understand the framework and be able to translate business needs into technical specifications. They should also have good communication skills, as they are responsible for explaining complex issues to non-technical people. They should also have strong math and debugging skills.
React developers often use Redux for application state management. Redux gives components direct access to data, and allows them to handle loading and error states. It also allows for caching data between views, which is useful for large apps with large data. This feature is especially helpful when the component tree is complex and the data is being forwarded through many layers.
React developers also need to have a strong grasp of CSS and HTML. They should also have flexbox and box model skills, as well as knowledge of CSS selectors and border boxes. They should also understand the Document Object Model (DOM) approach, which breaks a complex UI into simpler components. It also allows for nesting child components within parent components.
