React is a powerful JavaScript library for building user interfaces, known for its efficient rendering process and component-based architecture. When you write React code, there is a well-defined process through which it gets executed and ultimately displayed in the browser. In this article, we’ll dive into the details of how React code is executed, from writing JSX to the final rendering in the browser.

1. Writing React Code with JSX

When developing with React, you write code using JSX (JavaScript XML) syntax. JSX allows you to mix HTML-like code with JavaScript, making it easier to create UI components in a more declarative and readable manner. Here’s an example of JSX code defining a simple React component:

import React from 'react';
