What is the difference between JS and JSX? ›

Here are the key differences: Syntax: JSX is a syntax extension for JavaScript that allows you to write HTML-like code within JavaScript. It introduces XML-like tags and attributes to create React elements. JS, on the other hand, is plain JavaScript code without any special syntax or extensions.

JS is simply a scripting language, adding functionality into your website. JSX is an addition to the JavaScript syntax which is a mixture of both HTML and JavaScript. Both JS and JSX are interchangeable but JSX makes the code easier to understand for users.

React and JavaScript are two crucial elements of these ecological systems, which frequently cause misunderstanding owing to their interconnectedness. While JavaScript is the main programming platform for designing websites, React is a JavaScript package that simplifies the construction of graphic user interfaces.

Why JSX ? It is faster than normal JavaScript as it performs optimizations while translating to regular JavaScript. It makes it easier for us to create templates. Instead of separating the markup and logic in separate files, React uses components for this purpose.

Browser does not understand JSX directly. Because it's not valid JavaScript. So, to make it browser understandable there needs a compiler/transpiler which is called Babel. You can set up your own babel configuration or use vite or create-react-app which internally uses Babel for the JSX to JavaScript conversion.

JSX lets you write HTML-like markup inside a JavaScript file, keeping rendering logic and content in the same place. Sometimes you will want to add a little JavaScript logic or reference a dynamic property inside that markup.

JSX stands for JavaScript syntax extension. It is a JavaScript extension that allows us to describe React's object tree using a syntax that resembles that of an HTML template. It is just an XML-like extension that allows us to write JavaScript that looks like markup and have it returned from a component.

The primary difference between something like JSX and something like JSP is that JSP is a template language that includes a bit of java for the logic. JSX is javascript with a syntax extension to make it easy to construct fragments of html. The emphasis is different.

Community and Ecosystem:

In conclusion, ReactJS brings several advantages to web development that go beyond what plain JavaScript offers. Its component-based architecture, virtual DOM, declarative syntax, and efficient state management make it a powerful tool for building dynamic and interactive user interfaces.

React doesn't require using JSX, but most people find it helpful as a visual aid when working with UI inside the JavaScript code. It also allows React to show more useful error and warning messages.

What is the disadvantage of JSX? ›

JSX as a barrier

ReactJS uses JSX. It's a syntax extension that allows HTML with JavaScript mixed together. This approach has its own benefits, but some members of the development community consider JSX as a barrier, especially for new developers. Developers complain about its complexity in the learning curve.

People praise its pet policy. And perhaps most appealing is the fact that you can board a JSX flight without ever stepping foot in a standard airport terminal. And it might not be that much more expensive than a standard flight. Some routes cost as little as $300.

Advantages of React in 2024 over Javascript

Highly initiative: ReactJS is highly intuitive to work with. It offers interactivity to the layout of any user interface. Not only this, but it also allows fast, high-quality, and scalable application development that saves time.

It is used with React to describe what the user interface should look like. By using JSX, we can write HTML structures in the same file that contains JavaScript code.

JSX is not a requirement for using React. Using React without JSX is especially convenient when you don't want to set up compilation in your build environment. Each JSX element is just syntactic sugar for calling React.

JSX (JavaScript XML, formally JavaScript Syntax eXtension) is an XML-like extension to the JavaScript language syntax. Initially created by Facebook for use with React, JSX has been adopted by multiple web frameworks.

JSX is a statically-typed, object-oriented programming language designed to run on modern web browsers. Being developed at DeNA as a research project, the language has following characteristics.

Even though JSX had been around before React, it wouldn't have been nearly as popular without React picking it up. However, we can actually use JSX without React, and it's not that difficult either. The way React works is by configuring your bundler to convert JSX into calls to a createElement function.
