How does babel-core.OptionManager work?

babel-core.OptionManager is a class that handles the management of options and their defaults in Babel. It provides methods to parse, validate, and normalize options passed to Babel's core functions. The class also handles merging options from different sources and provides a convenient interface for plugins to access options.

const babelCore = require("babel-core");

const optionsManager = new babelCore.OptionManager();

const defaultOptions = optionsManager.getDefaultOptions();
const userOptions = {
  /* user-provided options */
};

const options = optionsManager.init(
  Object.assign({}, defaultOptions, userOptions)
);

In this example, we create a new instance of the OptionManager, retrieve the default options, merge them with the user-provided options, and then validate and normalize the resulting options.
