@babel/plugin-transform-parameters transforms ES2015 function parameters. This includes features like default parameter values, rest parameters (...args), and destructuring. This plugin allows older JavaScript environments to execute code using these modern parameter features by converting them into equivalent, backwards-compatible code. It targets situations where these parameter features are used, ensuring compatibility without needing to refactor your source code. Essentially bridging the gap between modern syntax and older environments.
