Why Should I Learn React?#
Still, the question remains: why should I care about learning React? What's in it for me? Here are five reasons to help you decide whether you should invest your time in learning React:
- Job opportunities: React is one of the most in-demand programming languages, with many well-paying job opportunities available, including remote work. This means that you have the potential to work from anywhere without being tied to a specific location.
- Versatility: React can be used for a variety of tasks, including but not limited to building highly dynamic or fully static pages, server- or client-rendered applications, and even desktop or mobile apps.
- Scalability: React's component-based architecture can help you write scalable and maintainable code with reusable components. It abstracts common tasks, such as state management to help you write less code.
- Performance: React uses several optimization techniques under the hood to efficiently update and render state changes. This makes it well-suited for building interactive applications where performance is a priority.
Fun fact: The early prototype of React was called FaxJS.
Show Me How React Works#
Let's take a look at a simple example to see how React works. To demonstrate conditional rendering and state management in one component, take the following code as an example. It renders a counter that can be set between
- Line 4: We create a new state for the component using the
useStatehook. Its initial value is 0.
countis the state, while
setCountcan be used for updating the state.
- Line 6: Whatever is returned from the component will be rendered on the page. At any time, there can only be one element returned from a component. Using
React.Fragmentensures we don't end up with wrapper
divsin our DOM.
- Line 9-13: We conditionally render the "Increase" button if the
countstate is less than 10. This can be done between curly braces using a logical AND operator.
- Line 10: Using the
setCountupdater function, we increase the count by one. This will render the component with the updated state.
- Line 14-18: We do the same for the "Decrease" button. We only render it if the
countstate is greater than -10.
Where Should I Start?#
Once you are familiar with the basics, you can dive into using React hooks. When you are comfortable building all types of components, you can start exploring more advanced concepts, such as portals, lazy loading, or suspense. We also have a guided roadmap that teaches you everything you need to know about React.
We also have a collection of custom React hooks that can help you get a better understanding of the world of hooks. Additionally, you can filter for React-related tutorials on our search page.
Last but not least, you can find all of our latest React tutorials below. Use the filters in the sidebar if you want to narrow down the results. I wish you good luck with learning React!
