What is a Preset in Webpack?

I started studying Webpack, in the article the author installs Babel, babel-core, babel-loader, etc. then explains what's what, here is the text from the article

"babel-core: Converts the ES6 code to ES5. babel-loader: Webpack assistant for code transpiling, sets presets. babel-preset-env: A preset that helps babel convert ES6, ES7, and ES8 code to ES5 code. babel-preset-react: A preset that converts JSX to JavaScript. "

But I'm not do you understand what Presets or Presets are? what is it and what is it for?
