@babel/plugin-syntax-jsx enables Babel to parse JSX syntax. JSX is a syntax extension to JavaScript that allows you to write HTML-like structures within your JavaScript code. This plugin doesn't transform JSX into JavaScript; it only allows Babel to understand the syntax without throwing errors. It's a foundational dependency for any Babel configuration that needs to process files containing JSX, often used in React projects. Without it, Babel won't recognize JSX tags.
@babel/plugin-syntax-jsx downloads show a general upward trend from March 2024 to August 2025, peaking in July 2025 at over 192 million. September 2025 downloads are significantly lower (around 46 million), reflecting that the current month's data is incomplete.
