JSX (JavaScript XML) allows us to write HTML-like structures directly inside our JavaScript code.
1The Component Philosophy
In traditional development, you keep logic (JS) and structure (HTML) in different files. React argues that they are inherently coupled. JSX lets you build Components that contain both. This 'separation of concerns' is based on functionality rather than file type, leading to more maintainable and reusable codebases.
2Expression Embedding
One of JSX's greatest strengths is the ability to inject logic directly into your UI. By using curly braces { }, you can evaluate any valid JavaScript expression—from simple variables to complex function results—right inside your tags. This makes dynamic rendering effortless.
