JSX vs JS – Which is the IDEAL choice for React?

JS or JSX – Which is the BEST for REACT?

When it comes to React, JSX (JavaScript XML) is the preferred way of writing components as it offers a simpler syntax that closely resembles HTML, making it easier to read and understand. JSX also allows developers to write code that closely resembles how the UI will look, which can improve code maintainability and readability in the long run.

JSX is essentially a syntax extension for JavaScript that allows developers to write HTML-like code within JavaScript files. By using JSX, developers can write components that render UI elements in a more declarative way, which can result in cleaner, more readable code.

On the other hand, some developers may prefer to write React components in plain JavaScript, without using JSX. While this is certainly possible, it can make the code more cumbersome and difficult to read, especially for larger projects with a lot of components. Additionally, using plain JavaScript without JSX can result in more verbose code, as developers would need to manually create and manipulate DOM elements using JavaScript functions.

So, which is the best choice for React developers – JSX or plain JavaScript?

In most cases, JSX is the preferred choice for writing React components. Here are a few reasons why:

1. Syntax Simplicity: JSX makes it easier to write and understand React components, as it closely resembles HTML syntax. This can make it easier for new developers to get up to speed with React and maintain existing codebases.

2. Readability: JSX code is generally more readable and easier to maintain compared to plain JavaScript. By using JSX, developers can write UI code that closely resembles how it will be rendered, which can make it easier to spot bugs and make changes.

3. Tooling Support: JSX is natively supported by React and most modern JavaScript tooling, making it easier to integrate with other libraries and tools. Additionally, tools like Babel can transpile JSX code into plain JavaScript, allowing developers to use modern JavaScript features while still writing in a familiar syntax.

4. Performance: While JSX code needs to be transpiled into plain JavaScript before it can be executed in the browser, the performance overhead is minimal. The benefits of using JSX, such as improved code readability and maintainability, outweigh any potential performance drawbacks.

Overall, JSX is the preferred choice for writing React components due to its simplicity, readability, and tooling support. While some developers may prefer to write components in plain JavaScript, using JSX can help streamline the development process and make it easier to build and maintain large React applications.
