How JSX is compiled in React?
Since JSX compiles into calls to React.createElement , the React library must also always be in scope from your JSX code.
If you don't use a JavaScript bundler and loaded React from a \x26lt;script\x26gt; tag, it is already in scope as the React global..
What does React run on?
Create your React app
- Open a terminal(Windows Command Prompt or PowerShell)
- Create a new project folder: mkdir ReactProjects and enter that directory: cd ReactProjects
- Install React using create-react-app, a tool that installs all of the dependencies to build and run a full React
.js application:

Why does React need to be compiled?
Both Angular and React deliver the UI as JavaScript: The UI that the end users interacts with in the browser is the result of JavaScript code that has created/manipulated the DOM.
In both cases the JavaScript code that is executed in the Browser is generated by a compilation step..
- How does ReactJS work? React creates a virtual DOM in memory to update the browser's DOM.
The virtual DOM will try to find the most efficient way to update the browser's DOM.
Unlike browser DOM elements, React elements are simple objects and are cheap to create. - If you're interested in playing around with React, you can use an online code playground.
Try a Hello World template on CodePen, CodeSandbox, or Stackblitz.
If you prefer to use your own text editor, you can also download this HTML file, edit it, and open it from the local filesystem in your browser. - Internally, React uses several clever techniques to minimize the number of costly DOM operations required to update the UI.
For many applications, using React will lead to a fast user interface without doing much work to specifically optimize for performance.
