Nodent-compiler is a JavaScript module that transforms ES7 keywords `async` and `await` into fully ES5-compatible code, enabling asynchronous programming without runtime overhead. It's designed for Node.js developers who want to write modern, readable asynchronous code while maintaining compatibility with older JavaScript environments. The compiler offers flexible options for source mapping, promise handling, and ES6 target compilation, making it suitable for both development and production use cases where performance and compatibility are critical.
